The only iOS 13 bugs I’ve been bitten by are: 1. Safari’s back button now seems to lose the position on the previous page - sometimes. 2. The share sheet has a row of Messages contacts that I didn’t ask for, don’t want, and can’t turn off - and it creates the risk of super-inappropriate sharing, because all my work contacts are eligible for being on this row, seemingly at random.
God this, my number one share contact is my ex, who i broke up with almost 5 years ago, and literally havent contacted in over 4. This person isn't even a contact in my contacts anymore, yet still top HOW.
I used to have the same problem until i took the plunge and just banished everyone i didn't like out of my digital life. If i don't want to interact with them, i just make their contacts poof/block them
