Okay, so it seems more and more people are experiencing this now. We imported around 5-6000 blog posts and it completely destroyed all performance in both the editor and designer when adding new blog posts. Webflow is advertised as “no problem” moving over “thousands of blog posts” from.
It’s been two months since I reported the problem and no fix yet. I have no idea if anyone is actually actively working on anything or what’s going on. Support is just saying they’re still looking into it.
Bottom line is, at the time of writing this, I can not recommend using Webflow at all for blogs or anything that’ll fill up the collections (even though we’re not even close to filling anything, as we’re running the 10k option).
