Tap search button on the bottom.

Search like normal for communities with the search term. Results returned like normal.

Clicking the unfilled heart (to subscribe) results in the error presented in the attached screenshot.

The back button (Android) doesn’t work. App must be force-closed.

The subscribing action was successful; discovered on reboot.

Repeating the steps, but instead of the unfilled heart, clicking on the community successfully navigates to the community.

This didn’t happen before.

I might be one update behind current as of Mar 18
