I agree. Official support has gone downhill massively as well. I've got two tickets that have been open for over 2 months and only had one reply in that whole time.
But back on topic, not sure if it's the Covid effect, the Marketplace change, the new version of the software or a combination of all of them, but support in general, save a very small minority of good devs has dropped off a cliff.
I'm waiting til the end of Feb when my hosting is due for renewal and more than likely will be moving to Wordpress, it's free, okay it might not be as secure (that can be dealt with), but at least its well supported, including the free plugins which some are even more complicated than the premium ones on the IPB marketplace
