The main problem is malfunction of desktop apps in the new libertine container. Any option is opened in a new window. Impossible to work with gimp or libreoffice, essentials for me. Firefox crashes as soon as it starts. I trust you will be able to repair these issues, but I just want a way to return to the OTA-3 version because the UBports Installer only installs OTA-5. The capability to run desktop apps is what makes this OS soo cool and unique, and would be a mistake loose it.
