The recent upgrade has not gone well and I feel sorry for the poor developers who were planning on a quiet holiday season.
I personally haven't found a way to work through the issues just yet. One thing is for sure, I'm trying different versions on different devices which is putting me into a situation where I need to unsync devices. With the monthly limit on my basic account, that creates a problem. Adding insult to injury, the system is asking me to pay for the upgrade 😕
