If uninstall Yatse does not work then the issue is 100% Kodi side
Yatse can only display what Kodi sends, sounds like a bug in Kodi that should be reported, there’s probably some cache somewhere there. (But you should reproduce the issue with web interface for example as naming Yatse won’t help)
Just to let you know. The solution was to first release all channel icons in Kodi, deleting cache of Yatse manually in my file manager and reinstalling Yatse.
I found out that reinstalling was necessary because i installed Kore to check what the PVR would show in that app.
So problem solved with a workaround.
Now trying to get noticed by the Kodi devs.
Uninstall Yatse does remove cache there’s nothing to remove manually
And using the clear image cache in settings does remove all images in cache so would have provided the same solution without the need to uninstall.
Let’s hope the root issue is solved on Kodi side (But if the image link is still the same after, in all case a Yatse image cache clear will be needed).
