This won't really answer your question as I haven't taken the latest update yet. I usually take them the same day but not this time.
I'm still on 13.1.2. Apps stopped crashing with this update but my wifi still comes on automatically every time I restart my phone. I only use wifi for Apple updates so this is annoying. Apple tech service contacted me so hopefully they address this sometime.
What problems are you having?
Again, sorry, I know this doesn't help you.
I'm sorry you are having issues with your device. What problems are you running into? Did this start after the software update?
