The application “1Password 7.app” is not open anymore.

Adding to the chorus of folks reporting this error. I've been experiencing it on multiple Macs, both Intel and Apple Silicon. It has persisted through multiple macOS Monterey and multiple 1Password 7 updates. The only thing I'm not sure of is whether it's been limited to macOS Monterey. I don't recall experiencing it on Big Sur. All my personal Macs have been on Monterey for a very long time but I've been stuck on Intel Big Sur forever waiting for my IT department to support it and don't recall experiencing the problem on this (Intel Big Sur) Mac. I have not previously reported this. I don't feel there's a reason when a Google search returns so many hits over such a long period of time. Also it's not limited to 1Password.

I upgraded to 1P 8 but downgraded due to loss of functionality (namely, cannot Command-n to switch between vaults) and other issues. You can search for my comments if you wish. I just added to a thread of complaints. Given that 1P can be used to store records that are not dependent on using a browser (secure notes, credit cards, identities, documents, bank accounts, driver's license, memberships, passports, reward programs, servers, and social security numbers -- some of these which have NO dependency on needing to use a browser and some that have dual purpose, I don't understand why you guys are intent on abandoning the desktop app.) Why should I have to launch a browser to access my secure notes, wifi passwords, social security numbers, etc. if I am not pasting into a web browser form?

My .02 cents. :-)
