I have had 5 (count them 5) NIB Solo's over the past several weeks and 100% of them have exhibited the same RC to AC disconnects. Flown in a remote area with no (app's verified) wifi interference. I assumed that I had an issue with my first Solo that did this.. assumed the same with my 2nd .. but 3rd, 4th and 5th I knew that it was Solo being Solo and nothing more. It's something to get used to for sure but it is what is is and why I will probably never fly in congested areas since I can't imaging how much worse the rage could get.
