Apologies if this has been covered before. But if so, I failed to find anything about it yesterday, after I noticed my Mavic Air 2 RC vibrating (not my phone).
The same thing happened again today. However, I noticed a Cessna 172 was not far away, and there was also a very small red aircraft icon on the radar screen - which I failed to spot yesterday.
So, if any other newbies like myself get the problem. The above may help.
