Lumy doesn’t have a sub, but it is a paid app. One time fee though.

Seems good for me too. Had to switch over to the developer channel as it wasn’t showing for me on public yet.

Super annoying that they provide no opportunity to downgrade. I didn’t even mean to still be on the beta, I’d jumped in for the 17.0 late betas and forgot to turn it off on this TV. My fault, but had no idea I couldn’t revert.
