Due to some other issues, Mac Support changed my Apple Profile and re-installed Sonoma 14.6.1. on my MacBook Air. Most of my applications worked immediately but a few had to be re-initialized. Quicken is the only one that still doesn't work. I will get a message that my data file is open on another computer. I use a Dropbox file for my Quicken data file and mainly access it via my Mac Studio. As a single user, I never need to, nor access, the file from both computers at the same time. However, when I access it via Mac Studio it says the file is open elsewhere. I over-ride that and everything is fine. But on the MacBook I get the same message but the override never works. I reiterate that I never have the file open at the same time on both computers. What should I do?
