When opening a file that uses a typekit font, Indesign attempts to "install" it (fonts that SHOULD already be there anyway, or were installed previously). The wheel spins indefinitely, and it never installs. My only workaround I've found is to attempt to find a download elsewhere on the web. Then it works fine. It seems to only be an issue with Indesign, and only since the 2020 update. Something similar happens with some non-adobe fonts, too. Says it's not installed, but it is.
