The numbers of members shown on the communities page (top left in BoostforLemmy Android) are the number of members from that specific Lemmy server, rather than the total number of members in the community.
If its a bug the can we fix this and if its not a bug can we get the total number of members across all servers shown?
This is an issue with Lemmy in general. They didn't respond to my feature request to recreate subscriber counts I made a couple months ago, sadly
Where did you make request? Post link here so maybe I and others can chime in...
They just closed it for being a duplicate of their own issue years ago https://github.com/LemmyNet/lemmy/issues/1440
