Hi,
I have the same problem, in the last 3-4 weeks it simply stopped working. I have 3 kids and my 70+ mother in the tracking. Microsoft doesn't care, it seems. Please provide a fix or i switch to Google services and start advertising your support capabilities experience I made as widely as I can on the internet. This service is crucial to me and it is not funny at all to have the ignorance of your service. I use in the family Samsung and Xiaomi phones with different android versions of the last 3. The problem therefore is hard to believe on my side. It is on the Microsoft side.
Thanks for your help in advance or good bye,
A pissed customer.
