If password reset works on mobile but fails on the web, report the same action on both platforms: request, email arrival, link opening, and password save. Record the app or browser version, approximate time, and visible error at the failing step. Make sure the two tests refer to the same service and recovery method before drawing a conclusion.
Do not post the account address or link. The difference may be due to app handling, browser state, or an account rule—not necessarily a global outage. A private window can be a useful comparison, but avoid clearing site data until you have saved any needed information. Use the official support route if the discrepancy continues.
