Hello. I appreciate you for bringing this up in the QuickBooks Community space, nika.
Please be informed that there's an ongoing investigation about an error message " Account does not include access. Looks like your account doesn't include access to the QuickBooks Online mobile app."
Our engineers are currently working on fixing the issue. In the meantime, I suggest reaching out to our Support Team to have your company details added to the list of affected users. Here's how:
- Log in to your QuickBooks account using a web browser.
- Click on the Help icon.
- Select Contact us.
Once you're added, you'll receive email updates as soon as new information becomes available.
In the meantime, I recommend accessing your QuickBooks account in a supported web browser: Supported web browsers.
I'm sharing the article where you can find details about the features available on mobile devices: Compare mobile app features.
You can add another post if you have concerns accessing your QuickBooks account on other devices.
