Greetings.
I'm not sure wether my problem is device specific or common for mobile version, but those game banners constantly make me go by their link while I trying to scroll. In simpler words, while I go on gog homepage and trying to scroll, I constantly go to the game my finger was while scrolling unless I'm very careful. It isn't happening in lists of games, for example in sale lists under sale banners.

It REALLY discourage from brousing games on gog from mobile devices. Which sometimes means at all. Is it just mine problem? Is there way to solve it? And no, I don't want to clutter up my phone with specific app for each site I visit, so no "get the super gog mobile app that we don't force upon you" promo please.

Hi! Same here, it seems to be a general problem. You could contact support and report it, if you want:

Using the site on a mobile has been a total pain for several years.

Then lets fix it. time to make a whishlist topic and vote the hell out of it. I mean they literally losing money because of it.

Also - is it normal that in the pc version adding my post is in different popup window? doesnt bother me yet but unusual.

Correct, a pop-up window.
