I have 1Password syncing to Dropbox. Added a new item on my Phone 13 today and it synced fine to my wifes phone but will not sync to my Windows 11 22H2 machine. Never had this issue in the many years I have used 1Password.
I removed the Edge extension and reinstalled. Exited Dropbox and restarted. Rebooted the machine. I have not exceeded the 3 device limit on Dropbox. I am about to do a reset all settings in 1Password but decided to check here first for anything obvious.
1Password Version: 7.9.832
Extension Version: Not Provided
OS Version: Windows 11 Pro 22H2
EDIT - resolved. Was a Dropbox issue caused by Dropbox update changing location of Dropbox folders.
