This thread is intended to consolidate questions and issues regarding the various Plex add-on that have come up with the Kodi v19 update. Any questions, issues, or solutions you may have please post in this thread and I will try to keep this first post current with the best information.
Composite
I did not find any issues with Composite. It should automatically update to a compatible version on its own without any intervention.
Plex (by Plex)
This add-on updates to the new version but did not work automatically under my testing. Doing an in-place reinstall also did not fix the problem. I believe the fix is as follows but I need feedback to verify.
To fix inside Kodi go to your Plex add-on, click the context menu, and select information and then click uninstall. When prompted select yes to confirm uninstall and also click yes to removing all related data. Reboot Kodi and then reinstall it again by going to add-ons>install from repository>kodi add-on repository>video add-ons>Plex>Install
This should then ask you to authorize the machine again.
Alternatively one might be able to just ssh into their box run the following to avoid having to reinstall the add-on…
rm -r ~/.kodi/userdata/addon_data/script.plex
systemctl restart mediacenter
One more alternative that I have not tested is to login to your Plex server and go to the settings and then authorized devices. Remove the authorization for your “Plex for Kodi” device and then see if the add-on will load (maybe try rebooting Kodi if it doesn’t at first).
If after getting Plex for Kodi working you experience delays in playback start, messages about bandwidth, and/or crashing after playback start then it may be due to a bug in the server authentication. In your Plex Servers settings browse to Settings>Network>List of IP addresses and networks that are allowed without auth
and clear all IP addresses in that field so it is empty and then click on “apply changes” at the bottom of the page. You may have to reboot Kodi for this workaround to take effect. More information can be found [here].
PlexKodiConnect
Upon update your Kodi library will still be there but none of the links will work (assuming it was setup with Plex links and not direct paths). There will also be a repository still present but it will be to the outdated Kodi Leia branch. The PlexKodiConnect add-on will be disabled. To fix this you should only need to download the following repository in a zip file and install it.
https://croneter.github.io/pkc-source/repository.plexkodiconnect.Kodi-Matrix.STABLE.zip
This will both update the repository and update PlexKodiConnect to the new version for Kodi Matrix. It should also automaticly kick off the install wizard, which will reboot Kodi (after you accept the prompt) and refresh the library which may take a bit of time.
If that didn’t work as planned please see the following…
