I had over 200 hidden cards when I updated, now I can not find any place to un-hide them and where did the website go? I tried reading the user guide but it had little to say bout the options. I like the filters form beore and used them all the time, like show only "what ever" such as show only cards that have updates. Or show only my favourites. Filters and favorites seem to be gone all together.

PS not even sure I can find this post again :-( I hope you get an email when there is a reply.

Go to 'my collection'.
Click 'filters' on the far left.
