SmartThings (Samsung Connect) UI Update - Android 1.7.27-25, iOS 1.6.27

I had 64 items well integrated and working well on SmartThings Classic until I made the mistake of opening the latest version of the Samsung Connect app. BIG mistake.

On opening the Samsung Connect app it created a new location and moved all but the shades to the new location (Home). It also made available only 16 of the 64 items to be manually controlled. There is no way to add to rooms, scenes or anything I can actually use to control beyond the 16 units. Oddly if I want to create automation I can include all of the other controllers but can’t operate manually any that weren’t the original 16 transferred.

My goal is to stay with the classic. I would like to consolidate all units back to one location since I only have one house. If I delete the newly created location what happens to all of the items associated with this location?
Is there a way, short of talking to the impossible to reach support, to re-associate the location to the old location? Has anyone solved this problem?

One option is to go through each of the 64 items and remove them from the network and reconnect them and redo the automations with a clean location. A fresh start. I would rather not do that. I’d like to find a way to revert to what I had three days ago.
