It's still under 3 months since the last update.
There's not really any giant bugs to squash, there's no features missing that are vital (tbh, I would say that there's really only two or three QOL features missing).
I'm not sure why people think apps need constant updates. Once you're stable, and sync is, you can take time to handle minor bugs and feature changes. Hell, it's better to handle those, test them well, and only then make an update, compared to cranking out untested stuff monthly.
And, with your post here in specific, why the fuck does a dev have to waste their time and ours popping in to say anything? Makes no damn sense at all. Idgaf how much an app costs, there's is zero obligation, or point to empty posts just to check in.
