I recently switched computers, and WonderLister 3 seemed much closer to the WL version I had used on my previous computer (WL 2? or even WL 1?), so that's what I have installed. More trouble than what it was worth attempting to restore my WL database from the old computer (long story, which I've posted about elsewhere), so I'm making do with the most recent batch of sold & unsold listings which WL 3 was able to import from eBay.
Now I'm trying to reconstruct my templates, which you'd think wouldn't be that hard, since I used those templates to create the most recent batch of eBay auction listings. However, WonderLister 3 is a newer version than what I used to have, and has a "GPSR" tab in the Listings Editor that I've never seen before, which is causing error messages making it impossible to save the templates I'm trying to create. I wish I could just get rid of that GPSR tab altogether, or find a minimalistic way to deal with that tab and get on with my listings.
WonderLister's User Guide may not be completely up to date, and the video tutorials are certainly NOT up to date (most of them are the same ones I used when I first switched to WonderLister 7 years ago). There are WonderLister Discussion Boards, but they might be moribund, as "forgot password" or completing the "contact admin" form seems to dump users to the WonderLister website home page. I'd be tempted to switch to another listing tool, but it seems everything else is even more expensive than WL's $5/month for the cheapest tier. (I so miss TurboLister!)
