I just purchased this setup this week and initially had trouble connecting the two as there is limited literature with the controller...I did get it going today and flew two batteries worth and then was unable to connect it again...it pairs fine with my phone but when I open the app it is not in the list...if anyone has any insight on this please reply...or should I just ditch the t1s and get another controller or the T1d I am using and iPhone 8...everything is updated (tello, app, and phone)
