I took a look at the code and Blizzard changed to the buttons being created when needed, instead of created when the addon loads. I'll keep an eye on this but think this should solve this and restore original functionality.

Hi !

Thanks for reporting this issue, I've made a change to disable this feature on Guild & Communities until a fix is done :)

This change should be available with the next update.
