Hello@"Peter Isakson"
Thank you for reaching out on the community and telling us about your issue. I have a small thing to try even though it's fairly simple. Could we try turning it off and closing the program. Reopen the program and then reactivate it afterwards. The option can be found across the top by selecting mobile & web > Remind me to sync to quicken cloud on exit. I'll leave a photo down below where to find the option as well.
Try closing to see if we're able to close it while doing the sync and exit properly. It's a quick attempt but I'm not sure if it'll fix it. Once you get a chance let us know how and if it doesn't work we'll see what our next best option is.
Thanks,
Quicken Francisco
