I have just visited this forum to ask something similar.
I have by and large switched from Dynalist to Obsidian, although in some respects and for some specific purposes, Dynalist is better than Obsidian.
I cancelled my Dynalist subscription after 5 years, then after a few months of the non-usable (for me, anyway) “lite” version, renewed my subscription for a month.
I’m currently a paying Dynalist subscriber, officially entitled to “Priority Support” via email, I have now sent the same query to Dynalist customer support twice, it was acknowledged via an automated message, but that’s it. No further reply from a human being. It’s been a couple of weeks now.
