I installed on my 15 Pro yesterday. It’s working just fine. I can’t say “happy fixes” because I had no problems at all with 26.1. Everything continues to work fine.
My wife still has 18 on her 13 mini and iPad Mini (though not for long) and occasionally doing things on her devices shows me that I still prefer 26 to 18. She hates when things change, so I’ve already warned her she’s not going to be happy about it.
