Hi have used app for a year with no problems. Bought a new Lenovo android tablet. Installed app. Channels are loading with guide. Problem is when I turn on ProgDVB engine to record half of the channels will not load. If I turn off engine the channels load normally and record. Android version 7.1.1 on tablet. Not sure what to do. Update i also have another tablet running android 5.1 and the app works perfectly all channels come up and also they all record. So proplem is only on newer tablet.
