I think that the lack of further attempts backs up what lj shared a bit ago in the Discord. That’s still a hell of a lot of tracking for folks who can’t or don’t want to pay, though.

It sounds like there will be a one time purchase option (Sync Pro) but I haven’t seen a timeline.

Personally, I’m doing the monthly subscription until Pro comes out. I appreciate that the dev got this beta up and running so quickly so I’m treating the subscription as a “thanks for your hard work.” Like you, I’m overburdened with subscriptions, though, and can’t maintain that long term.
