One Drive has Suddenly Changed on iPadOS 18.3!!!

I use MS365/One Drive on my iPad.  The other day, I opened One Drive and must have hit “Photos” bc that is where it went. I never use that option. I didn’t know how to get back to my files!!!!! But, I found the answer - go to the top of the screen and choose “Files”.   Which I did, but now the “template” is totally changed, the controls are at the top of the screen, and they’re different.  

Also, I can no longer drag and drop files/photos from OneDrive to iCloud or vice versa using Split Screen (I used to be able to drag and drop photos or files easily, now I have to go to “Share” and it’s more steps).

And, when I rename a file that template has changed - it’s a small box that is hard to see the file name  or type in and there is no “x” to delete the entire name.

It feels like I accidentally went into OneDrive photos and suddenly everything changed, it did not change the day I updated 18.3. I want the old view/functionality back. How can I get that?  I am on iPadOS 18.3 and OneDrive 16.3.5 thank you!
