Hi Ernie ;
I have deckes shared via protected group with join codes, THEY are being perfectly downloaded from IOS apple app but in android I am receiving attached error = ERROR INVALID COLUMN HEADER: EXTRA INFO --> this is the colunm where I have text it works (downloadable and viewable in apple) but in android its not recognized. After I had this message I also tried sharing the deck as private deck (via app server) and tried directly downloa by deck code, but same error. I think its prevalent in all kinds of downloading via android if the deck has an "extra info" column.
android is a newly downloaded version from google play.
I attached the error via android private deck download. - the video (via protected group deck download with join code I will email it to you).
