I had GX version 3.55 on my Cerbo and upgraded to 3.67 - however old UI not working anymore. How is this fixable or is 3.67 the end of the road for the old UI? With 3.55 both UI’s worked
Gui V1 is still working on VenuOS 3.67. There are some topics regarding this already in the forum. See e.g. this topic:
GX Remote Console : VRM : gui-v1 empty, no overview, neither settings etc - DIY - Victron Community
