I just finished the May 23 update on my 22 Kona Ltd Ev
I only had one issue. On completion of the installation cycle, the installation program started a second installation cycle on its own without permission or any interaction screen at all. I had to wait for another full installation cycle. When the restart screen came up I pulled the USB out and was given a "successful installation" screen.
It seems to work ok. Did anyone else have this problem or perhaps another problem?
