I haven't used the Collector App (classic) for some time, maybe one or two months, and now I find that I can't sign in anymore. I have both an Android phone and an IPhone. On both the apps got updated yesterday. On the IPhone I can still see my downloaded maps, but not the other maps. The downloaded maps cannot be synchronized, yesterday I received some error that there was no internet connection (but I could connect to the internet with other apps), and today it asks for my credentials, but does not accept the correct credentials (I used them to sign in to ArcGIS Online just now). On the Android phone it does not accept my account as well.
This is really curious. My colleague told me some users had a very similar problem yesterday and for that reason resorted to the Aurora app.
Is anybody else experiencing problems like this since yesterday?
Our local Esri support told me to clear the app cache, so I am going to try that and I'll let you know the results. I don't have production data in my downloaded maps, so I don't need to worry about losing data.
