Modern UI Changes Disappear

Not so much a question, but more of a confusion on my part.

I had an Acumatica hosted client today all of a sudden lose their Modern UI fields from a few customizations. Changes to a customization were applied Sunday and published. Everything was there this morning days later, everything was fine, then at some point in the middle of the day Modern UI changes disappeared. The customizations were still published, hence my confusion.

So I published them again and they were back. But why would they just disappear in the first place? Has anyone seen this? Or is there something I should be aware of?

I looked in the system monitor under system events and no events would lead me to believe there were any changes to the published customizations today otherwise (I filtered by Source for Customization and the only results for today were when I republished). It just seems so strange that I’m almost embarrassed to even write this post, but I’m legitimately confused.

I need to do some more testing, but I think this was triggered by changing the tenant’s Login Name.

Yes, changing the tenant’s Login Name does remove Modern UI changes. I would assume everything is tied to the tenant’s Login Name since reverting the change brings the Modern UI customizations back (or obviously you could also just publish again if you don’t want to change it back).

Not sure if that’s a bug or just a quirk from intended behavior.
