I just went through this in a very frustrating chat session. It doesn't make sense? They told me they have heard this numerous times and have escalated the issue. They advised I import into classic to watermark and then put them in CC to edit. Not happening. Who has time for that. I will definitely vote.
A lot of us in the community have been asking for this on mobile for a very long time. As this is now a whole ecosystem, it needs to be in all the CC apps. Hopefully by adding your vote, it'll help amplify the voices and this squeaky wheel will get oiled.
