I have a smart controller and a Mavic 2 Pro. During a short sunrise flight this morning I was taking photographs and after 5 minutes I couldn't get it to take a photo and then got a message that the app wasn't responding. It gave me a choice to wait or close the app. I ignored both and brought the drone down safely, turned both drone and then controller off and then back on. Took another short flight to make sure it was working...it was. Any ideas?? Thanks. (BTW...this was within the 30 minute before sunrise rule)
