Report the affected feature, when the change was observed, what is now working or failing, and the next check. Replace personal names, account IDs, addresses, and private screenshots with synthetic or broad descriptions.
For example: “Since 13:20 UTC, uploads fail on two browsers; downloads still work.” That conveys scope without exposing an account. If the issue involves one user, say “one account” rather than publishing its identifier. Verify attached logs for hidden tokens and URLs before posting.
A useful update is precise about behavior and restrained about private context.
