I invested a lot of time into strapi 3 - and dealt with the changes in strapi 4 with some client side transforms (a very poor solution I know) - but I think this will be the conclusion of most people looking at the data responses coming back from the server. Really hope it is acknowledged more and dealt with correctly. Strapi is a was a nice project but without addressing this issue I don’t see much of a future either. Unfortunately for me (and many I suspect) moving off will be painful, but necessary without changes. I wouldn’t have used strapi if I looked at Strapi 4 first as well.
