I got used to right clicking on cards to see the details on my computer. I played on my Tablet this morning and needed to see the details of a landmark but didn't know how to do it on the tablet. Perhaps this is user error? How do you right click on a tablet? If it can't be done, then this is an implementation issue for tablet users since you can't then look at the card details.
I don't have a tablet, but I think I've heard people mention that if you tap and hold that it right clicks? No idea which platforms this works on. Obviously still not a great way to access the card info, but maybe it can help for now.
Though yed reports that this method is currently not working in mobile Chrome with Dominion Online.
