Thanks
@Ferret. So I did the online update without backing any of my channel lists and settings beforehand. My mistake and admittedly somewhat lazy given the regular warnings from all of you.
The resulting "upgrade" to 1.30 removed my expiry and server connections to disconnected. Even so, I then proceeded to a factory reset, followed by another reload, followed by another factory reset.
Unfortunately, everything still showed disconnected. I then proceeded to load version 1.23 from USB and did a factory reset and all connections returned, but not all desired channels clearing.
I then did a USB upgrade to version 1.28, followed by a factory reset and the connections were retained and now all desired channels are clearing.
I will likely do a USB upgrade to 1.29 and factory reset, after backing up all my channels and settings and go forward. I will stay at 1.29 until advised otherwise.
One thing for sure is that I am only doing upgrades via USB from now on. No more online updates for me.
