Hi all.
I have a work made in Aquafadas (now Rakuten). The plug-in for digital publishing will not be developer again because the brand wil close the business. So, I switch the plug-in to another one (InPublishing) and everything goes fine on 2020. But with InDesign 2021 it seems to be impossible to work. InDesign 2021 made a ceck on files and it seems impossibile to add a file made with a plug-in that is not installed on a Book.
That's very stupid, because It seems that I cannot work with 2021 because the original plug-in is not installed. BTW the plug-in does not exist anymore so i cannot use 2021 or more?
That is a big problem because for the future I'm linked to 2020.

The thing I asked is to cut the ceck on files in 2021 like in 2020, so I can use my file with InDesign 2021. By the way, it's not an Adobe business if I use a plug-in or not!
