I'm seeing a serious problem with the GoG 2.0 app. If I do a search for anything, the results all link to oddly truncated pages without any purchase option.

Example: Searched for "Morrowind" and got a result list that included ELDER SCROLLS IV MORROWIND GOTY EDITION. However, clicking on the link took me to a page without all the usual information, including the price and without a "PURCHASE" button. However, if i browsed through the current special deals in the store until I found this game (i.e. without doing a search) then the product page looked fine and i was able to add it to my cart.

Seems like something worth looking into, if it keeps people from making purchases...

Are you talking about the galaxy client? Cos you don't need the client to access GOG.

Just click on the magnifying glass at the top right, type in e.g. Morrowind, and you'll get the link that takes you straight to the game page, so you can purchase it as normal.

Can't replicate.
Searching for "Morrowind" in Galaxy 2.0 gives me exactly one result: The Elder Scrolls III: Morrowind GOTY Edition.

It shows the price, discount and a mouseover "add to cart" option. Clicking on the result takes me to the store page, again with all relevant game and price info, "add to cart" button, etc.
