It happened already a few times and I suspected previously it occurred after some updates.
However, this morning I realised that on my private profile the two widgets I had configured have disappeared and I looked at an empty home screen.
In my work profile, the widgets were all still up as set previously.
And I'm sure it wasn't an update, as I definitely haven't rebooted the phone.
My main profile is empty and has nothing installed. So I'm curious what could cause these widget resets and if anyone else experiences that too.
