I know there are other methods to achieve it. I prefer the one tool to do the entire job without needing to patch in other devices.
Agreed. It can be a pain. I used to be able to prefetch Google Map tiles in MP for transfer over to Tower on my tablet. Google shut down the API for that though. The difference being that typically when I'm using Tower it's with my DIY rig which has 900mhz telemetry so I'm not bound to wifi and can tether that way. Bluetooth tethering can sometimes be a little flakey.
I've learned how to live with it. I've essentially quit using the stock Solo app and have been using Solex exclusively now.
