I'm not sure if you're talking about the same issue here, but we had a UI scaling problem on the mobile side after update 3-4 months ago, which was fixed (or cancelled whatever had been implemented with the update) shortly after.
The bug made everything in screen so tiny that it was "like trying to golf from a satellite" if I may borrow the expression of a user there in the thread. LOL
