Hoping someone will help I purchased a p3s 2 months ago and it as not been in a crash was working fine the last time I used it about a month ago. This week turned it on as was going to use it (fully charged) and wifi not showing in my wifi list. Tried to find the wifi with 5 other devices and still nothing. Took it back to dealer who refuses to look at it as I won't pay him if it needs fixing refuses to give refund. Have contacted DJI who does not respond what can I do to fix this
