Pulling-to-refresh the plugin screen should always result in the plugins shown in their correct state (active/inactive).
Despite pulling-to-refresh the plugins screen, it still showed an "old" state (inactive) of a plugin instead of its "new" state (active). It wasn't until I went to the site list screen and pulled-to-refresh there that the plugins screen finally showed the correct state of all plugins (as seen on the web).
In my case, I had a site with two plugins and a backup of that state.
I agree this should be investigated but would like to wait for additional feedback from users before raising this in priority in Groundskeeping, partly because I think Jetpack Plugins are a relatively low-traffic area of the app compared to some other areas where we are focusing work currently. This is always subject to change and open for discussion, so please push back if you feel it should be prioritized higher. Thank you!
Thanks @designsimply, I agree with the assessment. (I also corrected a few typos I'd made in the issue above 馃槃).
