IDML conversion unavailable.
I upgraded to CC 2019 and it offered to convert all my files (made with ID CC 2018) so I I agreed and it converted them. Turns out the plug-in of Math Magic I use for equations is not a valid plug-in for 2019, but works only for 2018 or before. As CC 2019 was just released, math magic doesn't have a 2019 version yet. I went back to using ID CC 2018 but when it prompts me to revert the files to CC2018, as it is unable to open CC2019 files, it says:
Unable to convert "Filename".
The IDML file conversion is temporarily unavailable. Try again later.
Please help. Don't have much time.
