Hi!! Adobe fonts are taking too long time to be installed! I guess this is an old issue, I used to have this same problem when this service was called as "Type Kit". I can see the problem continues, unfortunelly. My internet connection is Ok.
The way I have solved this is to click the info button on the font within the program, this takes you to the font page on the internet, if you click the activated font button to deactivate and then reactivate it usually fixes the issue within seconds. Haven't had an issue otherwise, little bit annoying but prevents long delays waiting for the font.
it is december 2021 and this problem still persist... let´s see if we can push it to 2022 (seriously shall i ask for a refund?)
Community guidelines ask that we be kind and respectful, however it is difficult due to the ongoing issues and disruptions that the Adobe suite has. Fonts should not be one of them. This IS a very expensive product and at the very least, fonts should not cause so many issues for the users. Fix this problem. (Oh, and Figma is killing it!)
