Both of my user accounts were Facebook ones. Now, after I've logged out, Activate runs a script which opens a browser window, and then automatically reloads the player account I just logged out of. I've lost the ability to change player. Yes, I've tried rebooting the iPad. Yes, I've tried closing the app, immediately after logging out. This behaviour began after the latest update.

Any suggestions?

Try going to your browser and logging out of facebook. Did Activate always open a browser for you to login to facebook? It seems that would be how they would do it, but I'm not sure as I never switch users. It seems that your browser is remembering you being logged in, so when Activate sends you to the browser and opens the facebook page, the browser sees that you're already logged in. You'll have to log out of facebook in the browser and try again. Like I said, I'm not sure how Activate handled that, before, but it always launched the browser, then it might not be Activate, but how your browser is now handling your facebook login. With that said, would Activate be affected by an update to Lost Islands? I would think that it would be the same across all apps, even though they aren't connected, just the same programming and not be touched by an update to the game itself. I almost think that when you connect to Activate, it's probably pulling the coding from an Activate site instead of the game itself.
