Garmin R10 Wi-Fi Connection Needed
One option is to open Awesome Golf Simulator using a direct Bluetooth connection while you have Wi-Fi and then while on the Main Menu, move to your hitting location. This is obviously not ideal.
Essentially, if you have an Internet connection at the time you are hitting shots, then your scores, PBs, etc, will be saved on your account, but otherwise they are gone. We don't try to store them up and wait for Internet to come back..
Options might be a Wi-Fi access point, like a TP Link RE650 or similar - this can connect to your Wi-Fi and extend it (this is previous gen tech). New "Wi-Fi 6" / 802.11ax Wi-Fi networks generally have much more reach. I have the Asus ZenWiFi AX (pair of 2), which has fantastic range and performance. Or a 4G router, although they don't seem to be 100% reliable at maintaining the connection in our experience, 4G directly in the iPad is probably more reliable if you have decent signal.
