I am capable of doing what you just said with any other airport besides EDDT, and I am familiar with how it is supposed to work like you have explained it.
Whenever I click EDDT on my favorites list it does not take me to the page where i am able to “unfavorite” (removing the yellow star) it.
I assume its because the airport is not in the database anymore.
let me know if you need a video to clarify what i mean.
How far off is the new Charts version and is there any other way to remove EDDT before that? Quite annoying to have it on the list when it doesn’t exist anymore.
Was thinking if there maybe was a way for you to remove it directly from a user’s account and the DB you use to store all user data. Because clearly it is stored somewhere since it shows up in the list for those of us who had it marked as a favorite in the past.
