Thanks for your informations about updates. I successfully installed these last updates and ran configuration wizard well without errors. I’m on SharePoint server 2019. Everything is running fine, except a few little problems on modern sites themes :
The top bar has lost the theme’s color and is now black, except for the apps button
The left navigation menu elements don’t have the background color when mouse is hover anymore
On classic experience, this doesn’t happen and changing theme of the site doesn’t help
It’s not a big deal, but I wonder why I have these kind of problems and how to solve it… If you have an idea?
