As someone who used Sync exclusively in the reddit days (and uses it here as well), while the dev is generally open to suggestions, he tends to take loooooong breaks, even between betas.

That means bugfixes and features do eventually come, but sometimes not before someone has moved onto something else with more active development. The funny thing is that when those updates do come, they come in speeding. Like multiple updates per day on some occasions.

I'm surprised you're able to continue using Liftoff at all. It doesn't work what-so-ever with any instance (like you can't log in) on any version of Lemmy beyond 0.19. I finally retired using it when my primary instance updated.
