I’ve converted 3 sites to EX. 1 went fine, a second wouldn’t convert until after the 4th try…then I had a lot of issues with it trying to modify elements. For example, I could not edit some text. Wix forms would not allow me to move elements to the same row for text. Interaction boxes needed to be reset. the 4th would not convert at all.
It is still VERY Important that all Blog Elements are available in EX. That the button controls are the same as they are for the regular editor. Also, one site had the Wix FAQ app, which did not convert.
Still the fact that I could even get it part-way there was a big improvement.
