Qb saying subscribed, google saying not - not been able to continue subscription since trial ran out

Let's verify your subscription status on a private window, 

There are times that an issue like this occurs when the system encounters any browser-related concerns.

You can use these keyboard shortcuts to open a private window:

• Google Chrome: Ctrl + Shift + N
• Mozilla Firefox: Ctrl + Shift + P
• Microsoft Edge: Ctrl + Shift + P
• Safari: Command + Shift + N

If you're able to verify the status, we can go back to a regular browser and clear its cache. A piled cache can also be the reason for some unexpected errors in the system.

We can also switch to a different browser like Google Chrome, Mozilla Firefox, Microsoft Edge, or Safari.

In case the trial period ends, you can check this article on how to resubscribe: Resubscribe or Reactivate QuickBooks Online.
