problem with signing in on the app

Hello Jack Ryan! 

Welcome to the QuickBooks Community! Sorry to hear you're running into this! The message you're seeing usually means your current plan doesn't include mobile app access. Intuit recently updated their software permissions, which has caused some older plans and specific entry-level tiers to lose access to the standalone mobile app This can happen if your subscription recently changed to a plan that doesn't support the app, such as QuickBooks Online Free or Lite.

To help us get you back into your account, could you please try these two quick steps?

• Log in via web browser: Try signing in at intuit.com using a computer or your phone's internet browser to see if your data loads normally.
• Check account status: Once logged in on the web, click the Gear Icon (Settings) and select Billing Info to check your exact plan name.

Please let me know if you checked and this is not the case. My team and I will investigate the matter further. See you in a few.
