Mystery at the museum not working on and Android 6.0.1

[+ian_canal_restorer]

I have an Android phone running 6.0.1 and app version 8.1.1, I have a 2015 galaxy a3 phone. Night at the Museum is not working, works fine on my Android 9 phone. if I select a cache with a clue against it, on my android 9 phone, and then on my 6.0.1 phone you can't see it. 

My android 9 phone is a work phone, so don't take it geocaching.

 

Any ideas?

 

Has anybody had this problem on older android phones.

Sorted now, reinstalled the app.
