Hi, I am creating an audiobook app. Once a user has recorded their audio, I upload the audio URL in Firebase under the ‘Voiceadded’ cloud variable, along with their UserID.
I would like the button ‘add your voice’ to only be visible to users who have not yet recorded their audio, and there userID is not in the cloud variable. I am trying to use ‘does list cloud variable contain UserID’ but it is not working.
Any help would be really appreciated!!
