Paid for 2 subscriptions now £11.99 and £14.99 and still saying my subscription is not valid

Congratulations on making your first post here, @Luke11_2. I've got some troubleshooting to sort out why your subscription is invalid.

Before proceeding, log in and out of your QuickBooks account. To isolate this, use a private browser to access your QuickBooks account. It doesn't retain local files to help rule out the possibility of a webpage issue.

Here are the keyboard shortcuts:

• For Firefox, press Ctrl + Shift + P
• For Chrome, press Ctrl + Shift + N
• For Safari, hold down Command + Shift + N

If this works, you’ll need to clear the browser's cache to start with a clean slate. You can also use other supported browsers as alternatives.

However, if the issue persists, I recommend contacting our Support Team. They can verify the status of the payments.

You can review these resources for more information:

Be sure to check back with me here and let me know how this goes. It's my pleasure to assist you further.
