I think something is wrong – Viewster Review

I just downloaded this app recently and it was great... but as of just now, I tried opening the app, and then it would have me signed out, and even when I try to sign back in, it would say “oops something went wrong”. I tried restarting my phone multiple times to see if it was just a temporary issue but something is seriously wrong here... please fix it immediately
