Saved Views, bookmarks, watches and personal labels are now account-backed. Signing out or clearing browser data does not delete successfully stored current records. Earlier browser-only beta records are separate and are not guaranteed to have migrated.
Check before recreating anything
Sign in with the account that created the records and check its access.
Open My Views and Emails → Manage Views and Emails or the relevant My Items tab.
Look for a load or save error and use the available retry action.
Check the source, label filters and whether another tab deleted or renamed the record.
For shared labels, check Org Labels; for personal labels, check Your Labels.
A missing sidebar shortcut does not necessarily mean a View was deleted. Check the management page and any hidden menu entries.
If it came from the earlier browser-only beta
Open the original browser profile if it is still available. Preserve any useful item links or filtered URLs before clearing storage. Migration of old local Views, bookmarks and labels is not guaranteed. Recreate an older query from its link or notes if it was never stored with your account.
Email preferences are separate
Use Settings and Notifications → Notification Centre for current email choices. Old report-page switches were browser-only demonstrations, not real subscriptions. Different old preview values do not mean your account-backed Views have stopped syncing.

Send the account and organisation, missing record's name or item ID, last time it was present, relevant URL and visible error. Do not assume recreating or deleting records will fix a failed load.
