I have the problem that sometimes zapping time is too long. It’s not the m3u list because the problem doesn’t exist on other apps like smart iptv. It is not always and not always the same channel. you can zap back and forth between two and sometimes it’s fast and sometimes you have to wait a long time. or click more often. it wasn’t the old version. this has been the case since 2 versions of the app. 1.5.9 releases and fire tv stick are used. It used to be smooth and fast and now it’s not much more. Buffersize 1 or 4 makes no difference when zapping. maybe a setting or something? please help, recommend your app to many customers and only your app is the problem.
