Quick answer
After Subscriptions 9.2, check who owns the subscription and generate a fresh link from My Account. The release tightens line-item removal permissions and gives removal and resubscribe operations separate nonces. Old links can stop working by design. Do not grant broader customer capabilities to make an old link pass.
Identify the exact action and actor
Write down whether the complaint concerns removing one item, resubscribing, or undoing a removal. These actions have different consequences. Also distinguish the purchaser from a gift recipient, a shop manager helping a customer, and a visitor who is no longer signed in.
Use separate browser sessions for the purchaser and recipient during testing. Signing out and back in within one tab can leave confusing page history. Refresh the account screen after changing users, and avoid screenshots that include personal order details or token-bearing links.
Check eligibility before debugging the link
An action can be absent because the current user is not eligible, because the subscription state makes the operation unavailable, or because custom rendering omitted it. Compare the same subscription in its normal My Account view with any custom customer portal.
The release means a custom filter alone cannot grant line-item removal beyond the ownership capability check. Calls without a user context also return false. If a background task used that helper as a general business eligibility test, review that code's purpose instead of impersonating a customer to work around the result.
Replace stale navigation, not authorization
For resubscribe, return to the current My Account page and follow its newly generated control. Do not bookmark a security-token URL or distribute it as a permanent customer-service shortcut. A saved email, browser-history entry, or cached fragment can still contain the old operation token.
The temporary Undo link shown immediately after removal has a different recovery situation from a normal account action. If it is no longer valid, investigate the actual item state and available supported recovery options. Do not invent a new URL or reuse a resubscribe token for a removal operation.
- Record the account relationship without exposing personal information.
- Check the subscription state and the exact item being changed.
- Use the normal account screen to obtain a current action.
- Verify the resulting item list, not merely the success notice.
Inspect customization on a staging copy
If the standard account screen works but a custom portal does not, compare the code that builds its links and controls. Look for stored URLs, direct string construction, and assumptions about filter arguments. Use the current plugin interfaces and preserve operation-specific checks.
Test the portal with an owner, a recipient, and a guest. A correct result includes denied actions for people who should not have access. Record those negative tests alongside the successful owner test. Testing only as an administrator can hide exactly the permission problem customers experience.
Keep personalized pages out of shared caches
Check whether the account page or its action fragments are being served from a shared cache. A private customer control must not be reused for another visitor. Investigate the cache configuration and response behavior; do not simply lengthen token lifetimes.
A public cache hit containing personalized account data is a separate security issue. Contain that exposure with the hosting team and review affected paths. Do not treat a cache purge alone as a durable fix if the page will immediately be cached again under the same rules.
Verify the business outcome once
On a sandbox fixture, perform one eligible action and inspect the resulting subscription items, totals, and renewal schedule. A control disappearing after the action might be correct. Avoid clicking repeatedly while waiting for the interface to catch up.
Keep a short outcome record: actor, relationship, action, source screen, expected result, actual result, and timestamp. That record helps support explain an intentional restriction without mislabeling it as a broken update. It also makes it easier to escalate a true regression with a reproducible example.

Ask for WordPress account-flow support if a legitimate owner still cannot perform an eligible action. Share the action name, role, subscription relationship, and a redacted error. Do not send a live action URL because it may contain a security token.
