Bug Report: Push/email for tasks has been broken since GPT5.1 launch
`Steps to Reproduce`
Create a new timed task. It shows under Schedules. Wait for it to run in chat.
`Expected Result`
Push/email received on iOS/browser/email- which all works fine for e.g. Deep Research or Shopping. This shows it is NOT a client-side issue.
`Actual Result`
No push/email, ever, regardless of date or time. Under Schedules, task is bizarrely listed as having run on 8/10 or 10/20, never any other date. The push server is receiving the wrong data or misinterpreting it.
`Environment`
Windows app, Windows browser (any), iOS app, iPadOS app - it's a server-side issue.
