Can't sync quicken to quicken cloud.
You'll need to sign out of the Mobile App and sign back in:
Note: The Mobile App is a companion app and requires the desktop Quicken program to sync data with. Make sure when syncing on your desktop that the accounts you want to sync are selected. In the Mobile & Web tab, you can see what accounts are enabled for Mobile Sync. If the accounts you want to sync are not listed there, you can click Edit Account Setting to add or remove accounts from Mobile Sync.
If you aren't seeing the data file you are expecting to see, try signing out of the Mobile App and signing back in. Also, make sure you are signing in using the same Quicken ID on both your desktop and mobile device.
You can read more about these instructions in the Support Article linked here.
I hope that is helpful.
