On the toolbar, there's a magnifying glass icon that I'm calling search.
I enter the search page by clicking on that icon.
On the search page, there are a number of communities, and at the bottom, there's a Random Community button.
When I click on Random Community, I am sent to !100yearsago@sh.itjust.works
So far so good.
When I backswipe to go back to the search page, and click on Random Community again, I get a yellow error dialog saying "Failed to find random community"
No choice but to go back to the search page.
Random Community again returns me to 100yearsago
Back and Random Community gives me the yellow "Failed to find random community" dialog.
Ad infinitum
Edit: I am using Android v2.9.1
It is working fine here (iOS)
I tried on my iOS device, v 2.9.1 and it's behaving similarly to what I describe in my reply to @pro_user@lemm.ee who told me about pulling down to refresh:
It seems to cycle between "Failed to find random community", !100yearsago@sh.itjust.works , and !categoryiii@lemmy.world - which is a /c that I subscribe to already
but in iOS v 2.9.1 it adds !3dprinting@lemmy.world , and wowthisnsfwsubexists@zerobytes.monster - which returns a "nothing to see here" message, and some Korean NSFW /c that has never come up again after coming up twice.
