Question Draw Something 2 doesn't remember credentials

So I have Draw something 2 paid version and I use my email address and password to login to use it. The issue is, the app consistently forgets my credentials the next time I launch it! It happens 8 out of 10 times that I have to enter my email and password when I open the app.

Has anyone seen this issue? Is the app just crappy now? It happened to me on my Galaxy S4 and happening on Galaxy S5 as well. Thanks guys for reading.
