simtracker not working properly

the simtracker only shows the first 2 sims. it wont swipe along to view my other sims. i cant advance in the game because i cant call more over to my house for the goals. also the hobbies/jobs one wont swipe over too.

looking through the reviews for freeplay on google playstore, heaps of other people are having the issue as well and have been for the last 2-3 weeks.
