For the past three days, I've tried the following:
Fix and validate:
When I manually import the transaction from my credit card (they post to a new account created in Quicken (I didn't ask for a new account)).
When I move the transactions to the correct credit card and then close Quicken, when I reopen, the transactions all disappear.
I've gone to Edit, Preferences, and disabled mobile. I tried to fix and validate the account; nothing works. I'm a 15-year Quicken user, but the quality of Quicken is going downhill very fast, and I'm very frustrated by support issues every couple of months.
