We have just released a new Android beta v6.29.1956
that changes server synchronization of favorites and hidden to a manual process. There is now an Import and Export button for each HDHomeRun and TV Everywhere source that can be used to pull and push the remote favorites and hidden channel settings.
This change is part of the work that we are undertaking to unify the behaviors between the Android and Apple apps. We plan on bringing back server synchronization in the future in a more flexibly way and this is a stepping stone for us to achieve that.
Please let me know if you run into any bugs or issues with how this works.
