Well maybe there should be a big banner on the Marketplace saying “Don’t panic! Although 90% of the content is flagged as incompatible with the newest version, it is”
Besides its not just products, its tutorials that also become obsolete with updates as I have found. Sure all does not matter a jot to anyone with experience, they will sort it out for themselves, but as I pointed out I am a new kid on the block just telling it like it is from a noob point of view.
