You will then want to sign out and sign back into the mobile app to see if you are now able to see your accounts.
Please let me know how it goes!
Are you using the same Quicken ID?First, verify that you are signed into the correct Quicken ID. The Quicken ID you sign into on the Mobile App needs to be the same one you use in Quicken on your computer. To verify the Quicken ID in Quicken on your computer, go to Edit > Preferences then Quicken ID, Sync & Alerts. On the Mobile App, sign out (located in Settings) then sign back in using the same Quicken ID you just confirmed you're using on your computer.
Are you viewing the correct data file?After signing into the Mobile App, you will be given a list of data files associated with your Quicken ID. Here you can select which data file from Quicken on your computer you want to view on the Mobile App. If you are missing transactions on the Mobile App, make certain you are viewing the same data file you have open on your computer.
Using a different Quicken ID or viewing a different data file can give the appearance that information is missing from the mobile app.
Please let us know what you find!
