Have been using 1Password on Windows, and the 1Password Pro app for iPad for many months without problem.
But in the last week, the Windows version no longer displays all folders (eg "Email accounts" folder). I have 21 folders in total, but only 14 are visible. If I select the "All Items", the underlying entries are still in the database (thank goodness), On my iPad, all 21 folders display.
If I "add" a new folder (using the Windows version) with the same name as those that are hidden, that will create an empty folder (ie not restore the missing folder), but then 2 folders with the same name display on the iPad app, one with entries and one without.
I recently installed the Pro app on my spouse's iPad, and linked to the database, but it only displays the same folder list as the PC, not the full folder list as displayed by my own iPad.
I have today updated to version 22.214.171.1248 and that makes no difference to resolving this issue.
