Did the OTA.
Did the Clean install and restore.
Did the Clean install and manually add.
Fixed some things, broke others. Some things changed without changing anything.
It does work for some folk. It doesn't for others.
iOS 13 is pretty darn good. However there are some issue which while not 100% for all users does cause issues.
XS MAX on iOS 13 PB4
Here is an example of "it changed and I have no clue why ..."
I have posted previous example showing how the Unread totals in stock email are incorrect, and All Inbox unread shows incorrectly once all emails have been read.

This morning, likely caused by my complete reset and redo of PB4 on my XS Max. Today, this morning, that all changed.
I opened stock email, the total email unread in the accounts no longer matched the total posted in All Inboxes. This was new.
So I went ahead and read all my unread emails. The accounts now show empty. Now, All Inbox unread total is correct.
However, now my GMail app is having issues. It shows the number of unread in the Badge which matches the actual number of unreads. But ...
After reading all the emails, the app badge doesn't change. Even if I manually refresh. I have to kill it in the task manager to get the correct value.
Fixed one thing, broke something else
