Well I've got half a decade on you and 25000+ users. Anytime I hear something like this I get all parties to duplicate the issue in front of me.
Mysteriously the issue can't be duplicated and magically resolves itself.
Yes, fake news doesn't work in our profession. You have to look outside of your worldview and feelings so you can get the info and solve the problem.
Right i'm a liar and just wasting my time here IM DONE HERE!!
I'm not sure if you're a liar but I'm pretty sure you are not looking at this correctly.
I suggest looking outside of your worldview. You have to look at the data. Millions of iPhones and Android phones with these chipsets and people using the same platforms are within meters, feet and inches of each other all the time. Millions are on same networks at same time. It would be front page news if what you had occur were possible or happened by small percentage points.
You should also consider the platforms here - the phone OS plus the Google user base - are huge. It's 10s to 100s of of millions of people if you look at iCloud, Google & Microsoft as examples. People and news react to things that are small by percentage. We'd all know this problem if it existed.
As two of us with experience have said, this is probably a mistake with your setup, credentials, and/or not fully understanding what you've shared with someone else. I see versions of this problem often and they go away when the people with them do the looking and learning with the right mindset.
Good luck.
