Welcome back!
1) Not sure I understand the problem... a log with some details will be required.
2) YES! Discovery+ recently added support for the same method i'm using in my other plugins... https://github.com/add-ons/service.iptv....-766367596 
However, in order to make import seamlessly integrated into PseudoTV, a few extremely small tweaks need to be made to the Discovery+ code.

I did a quick test with the IPTV manager addon yesterday using the Discovery+ live channels. I noticed that the IPTV manager added all the live channels from the Discovery+ addon. Since I already have half of these included on my regular satellite service I didn't really need all the channels. Maybe be better if users could choose beforehand what channels they actually want imported into the IPTV client.
Anyway, I added another couple of Discovery+ channels to my own custom m3u file afterwards and then tried importing again, using yesterday's PTVL update -  Version (g). Actual channels were imported fairly quickly (less than 5 mins), but without any guide data. I then tested again using the IPTV client and all 3 channels with guide data were picked up immediately. After rebooting Kodi a few times, PTVL also added both the channel and guide data, but probably took about 15-20 mins to add the guide data part. So all 3 channels now working without issue with PTVL using the Discovery+ addon. Will add the rest of the channels I'm wanting now! 
Only real issue was PTVL not picking up the channel logos when I added them to the logo folder. In the end, I changed the logo path on my custom m3u file and then changed the setting in the IPTV client to use the m3u file for channel logo paths. But that means I need to do that each time I start Kodi, so probably not the best solution.
As for 1) from my original post of yesterday. Yeah, I will post a full log asap, but was thinking it might a good idea to try and record what is happening as well when start Kodi.

Any control of channels added to the IPTV manager from Discovery+ has to be controlled on its end. For example, my plugins: Locast, PlutoTV, ChannelsDVR include an option to "ONLY ADD FAVORITES" and a context option to flag channels as a favorite. When it comes to PseudoTV's mass import feature ie. "Recommended Services" no control will be included... it functions to import a third-party list, management of that list is out of the scope of the feature.

When using PseudoTV Live, IPTV simple logos are only detected if they are in pseudotv.m3u. If you are importing a third-party m3u logos must be included in that m3u list which is imported to pseudotv.m3u. PseudoTV Lives logo folder is only used for channels created by PseudoTV... "Pre-defined", "User-defined".

As for what you described, the only issue I can think of is the PVR background is refreshing which will cause meta widgets to blank out while they refresh... this is normal. PseudoTV Live will only force the PVR to rebuild when there is no playback... this is performed hourly or if you recently made changes to Pseudos settings.
