I've noticed this issue popping up a few weeks ago. Using the trial version is the only solution at the moment. Furthermore, you can use it permanently to access your historical data.

I understand the urgency of this matter. Since the Community space is a public forum, I don't have the secure access needed to view your account files or look into specific case details. You may consider reaching back out to our QuickBooks Live Support team for follow-up and to check on the status of your "View-only" access mode.

Feel free to leave a comment if you need help with any QuickBooks concerns.

Why did you decide switching to QB Online?

You can use the trial version of QB Desktop to permanently access your historical data. Alternatively, you can resubscribe your QB Desktop license through a reseller and get competitive pricing. However, if you'd prefer to switch to QB Online but the conversion isn't working well, you'll need an alternative solution.
