The gang at ‘Round Android Smartwatches” ( https://roundandroidwatches.proboards.com/ ) have a Youtube channel now. They’re not Amazfit Pace specific but cover a wide range of round smartwatches based on Android. Many of the apps they’ve tested do work on Amazfit Pace. ( sadly, not the universal watchface launcher ). The videos have recently started and include topics of value to Amazfit Pace owners as well.
