It appears that the “OK button” was moved from the right to the left in the Update Plugins dialog in the latest MainWP Dashboard release. I’m sure I’ll eventually adapt, but years of muscle memory has been invalidated!
Me too We moved those buttons to be more in-line with where WordPress adds their buttons in the WP Admin.
The good news is that I seem to be adapting rather quickly. The second update of the day happened without missing a beat.
