Hello @James Nail
Thank you for
reaching out on the community and telling us about your issue. I do apologize for the issue you're having. It sounds like you've already taken a couple of steps here to try getting it validated. Another thing I would attempt here would be to try to duplicate the budget then attempt to resync it. To do this if you go to the planning tab and in the top left select the cogwheel you'll get a dropdown with the option to duplicate the budget. Once it's duplicated it double check it's correct then select the original budget and select the cogwheel again to delete it. Once that's been done try resetting syncing with the cloud again.
I'm not sure if this will fix it another thing would be to try resetting the cloud after duplicating the budget as well. To do this you can navigate to edit > Preferences > Mobile and web > reset your cloud data.
Once you've given this a chance let us know if it helped. If not we'll see what we can try next.
Thank you for taking the time to visit the Community to ask your question.
The solution for me became apparent when I discovered that my cloud data was updating even though the message said sync failed. All EXCEPT the budget! I made a copy of the budget I was using (2020) and named the duplicate 2021 (since we're almost there). I deleted all my other budgets (2018, 2019, 2020). Then I did a "reset cloud data." Next I ran "One Step Update" which had no errors. Next I went to Mobile & Web tab and ran the Sync Now. No error message (Cloud data was not synced. Parameter Name must be specified). I logged into my https://app.quicken.com account and all the data is there including budget. Problem resolved!
