Hi Bmangt+
I deleted my wifi connection on my Samsung a53 5g and only connects the Bluetooth and USB lead as suggested by motochick previously, it takes about 30secs for the app symbol to appear on your bike dash but once that shows and the myride-link app opens I then open motorise in that app and I get a pop up message on my phone saying "phone connected and ready to mirror".
I create my routes on Basecamp then export to a folder on my laptop, once I have or my routes compiled I transfer them to a folder on my phone sd card then just share them to motorise. This can all be done well in advance of trip. I've got mine or sorted for our short trip in July and like you I'm always the leader of our group.
