From the Collection tab, if I’m on Wanted to add a new card, the page disappears with a warning that something went wrong and that I should refresh the page. This happens for every new card added from Wanted.
Can you open the developer console and tell us what the error is?
As an additional note, it doesn’t happen if I am on All view, just Wanted (haven’t checked For Trade). I used to select the Missing tab so I could sort by what cards I am yet to obtain.
Will be fixed by #810 that should be deployed soon
