After writing this, I see that @Garima Singhmentioned they've fixed a deselection issue. Hopefully that's the issue I'm experiencing. Just in case, I'll leave my post since I think it could help to further diagnose the problem.
Here's an exact thing that can be tested to show the issue. I'm doing it right now and the way the UI works makes things extremely difficult. I have a sub-tag with about 40 items in it:
Customers
Customer Name
MS365
I'm trying to update every item in the MS365 sub-tag and this is what happens:
Select the first item. Click edit. Update password. Click save.
Select the second item. Click edit. The second item gets deselected. The input form that's docked to the right of the screen closes.
Repeat for 40 items.
The item deselection definitely seems to coincide with the sync that happens from saving the first item, but, like @urgatorbaitsaid earlier, there seems to be more than one sync happening. Sometimes I end up with the item I'm trying to edit being deselected multiple times in a row.
An update or two ago it worked differently. The item would get deselected, but the input form would not close and I could at least finish what I was doing. Now the input form closes if I haven't made any changes or spams me with prompts to save my changes if I've made any.
