I haven't! And I have continuously played around with it.
I attempted:
1. removing all rooms; then it looks like you have no rooms and all your photos are labeled other, other1, other2, other3, shared other, etc
2. just tried removing photos but leaving the room descriptions. still your photos will all be listed as other, other1, shared other, etc and be individual so not grouped just looks like a million unassigned photos.
3. also the order can not be changed. i attempted adding only one room at a time and saving it thinking that would put it first, but it didn't. it always wants living room 1st. i have 2 living rooms so the best i could do was leave off that i have a 2nd living room and combine it in with living room 1 photos or allow it to be an "other" space.
4. shared other will always be last in your configuration, you have to name everything to not have unassigned photos just hanging at the end.
5. for the bedroom order i did notice i can manipulate it thru tedious adding and taking away. example: it puts the bedrooms out of order so the kids room #2 first then the 3rd bedroom then master then the 4th. of course i wanted the master to show up first. so i had to go into rooms and spaces, edit rooms and subtract one bedroom from you bedroom total. So making it 3 instead of 4. then i went back in added the 4th again. i assigned the photos and saved. when i refreshed the bedrooms were in a different order, #1, #3, #2, #4.
Does any of this help? haha not really!!! I can't believe it's been a year of this with no change. And booking is down for us all so every little thing helps like having control over your photo order and rooms! If I make any progress I will update here 🙂
