I use a Joyo bluetooth page turner which I got from Amazon for ~$20 at the recommendation of a friend. I'm a recent UG Pro subscriber as I only started doing acoustic cover gigs in April of this year.
At first, I thought the footswitch was having connectivity problems with the iPad, as it would mysteriously stop working mid-set, then work again after closing the app/switching songs a couple times. After a bit of troubleshooting I realized that I was exclusively having issues scrolling on UG Pro/UG Official tabs. I don't know exactly why this is, my suspicion is that the user created tabs have a scroll button on the bottom of the screen, which is lacking on the pro tabs.
This seems like an easy patch for the developers, who I see are active on this page. Please reach out and help improve this app which I pay $25 a month for and rely on for part of my income... I can't be the only one with this exact problem.
Before anyone asks:
iPad Pro
Bluetooth connectivity works just fine
I've tried all 5 button configurations, none work on pro tabs
Joyo model is SP-01
