Changing regions causes crash loop

This problem started about a month ago for me.

I can visit Limestone Cliffs region but when I try and leave the game crashes. Sometimes I can log in on another device and get back to the main city but for the past day I've not been able to.

Ive tried clearing the cache, data and reinstalling the full game. When I log back in it takes me straight to Limestone Cliffs and when I try and leave... We crash again.

I try to leave by selecting any other region. I've tried to visit friends and return but it still crashes. 

Occurs on my Samsung phone and tablet. Both are up to date.
