I did a poll and nearly 30% of the people who voted said they used Sync! It's stayed around that percent the whole time too!
EDIT: Here is the poll I forgot to put this here like five times lol https://strawpoll.com/wby5A21R1yA
I'm talking about other version numbering issues that all of Lemmy experienced at that same time. While the one you spoke about was Jerboa specific, I experienced the other issues on the web as well as on Sync. As you pointed out, Jerboa is developed in parallel with Lemmy and it seems like these issues were a blind spot for the developers.
