I know how difficult it is, @Ken B1. I want to ensure this will be taken care of. 

Thanks for posting here and sharing your insights about this. As of the moment, the option to go back to the old version is unavailable in QuickBooks Online (QBO). That said, you can send feedback to our product developer to send your comments or suggestions. Here's how:

1. In your QBO account, select the Gear icon.
2. Next, choose Feedback.
3. From there, enter your comments or product suggestions. 
4. Once done, select Next to submit feedback.

I've also added this helpful resource that you can access anytime if you need references and guidance in performing your QBO tasks: QBO Help articles page. 

Please know that you can always post here again if you have any QBO concerns. I'm just around the corner to lend a hand. Have a great day ahead and take care.
