Bug??

I finished my hellish work yesterday, eagerly anticipating the event, but the app update/installation wouldn't progress. Since I had work the next day and no time, I ended up not being able to play yesterday 🥺 It just wouldn't get past the loading or update screen. Was that a bug, or just an issue with my home's internet connection? I checked this morning and it loaded and showed the play screen without any problems, so it's fine now... but what was that all about??
