Problem is: Factory reset is not so easy for everyone. For example: I'm working since weeks in homeoffice because of the corona desease. I cannot reset and backup my phone, because it will not allow me the reactivation of the software token for VPN connections to my company. And then the connections for banking software and so on...
So my mobile device is - as for many - not only hobby or gaming.
For this reason Apple for me is (was) the first choice: Good working software based on known hardware.
This created the exception: I buy and use it as I need. For this reason I pay even a bit more.
If this will not work anymore in future, I can even setup a linux desktop and use android phones. It will work, but it
will cost me more attention.
In my case: Same problem. I cannot do a factory reset because of many disadvantages. I have a brand new watch but a not working apple watch app.
Or Apple finds a solution for the problem within the next days, or I will send back the watch within the 14 day return period.
I like the apple watch (had the series 4), but I do not pay money for getting frustrated only.
