I’m having the exactly same problem. :/

Same problem here. 

Hi everyone, 

I had the same issue, but it seems to be ok again now. Can you check your apps, and maybe reopen the app if you’re still having issues. 

Just tried again and still nothing :-(

Hopefully it’ll be ok soon for you @Andy.Dennington
