I had people in my Alliance who were playing on other devices an when they updated they found out they were no longer in my allince whatz up with that is anyone else having this issue???
It happened to some friends in my alliance. It seems it just takes a while to load that info, but if you mess with it you actually can be booted or something.
If the issue doesn’t self resolve, then definitely reach out to Small Giant at support@smallgiantgames.com 
Hope it all works out!
