I understand that the Adobe Reader mobile app have some free features and some suscription features. But, please, could you respond to a suscription client like me, why I can't add, modify or delete a bookmark on my iOS, when I am suscribed in the same suscription as an Android client? Please, this feature is requested since 2016 and I think 7 years is long enough to develop such a feature, so I don't want to read more nonsense excuses.
