Im having the exact same issue.
Back when i started using comp everything was working smoothly.
then all of a sudden. the ipad (adobe comp) reported the file was sent. but nothing opened on the computer.
back then i tried everything (This was in 2019 november'ish). testing with a Windows computer and a Mac laptop with up to date installations of the adobe package.
i was searching the internet thin for maybe a hint of a solution. but nothing was found :(
in the end i just gave up.
then now in 2020 i decided to see if i could solve the anoying issue once and for all.
and to my amazement i were able to send to all other programs than indesign, witch is the only program i need it to work for.
but atleast indesign opens now. with a the message attached to this comment. i have tried everything to solve this but with no luck.
only thing i dident try is reinstalling my computer completely. i am not willing to do that !
