When I have a very long collection list, and its size is greater than the total number of games that I am showing, I cannot select any collection that is below the total number of games shown.

I have tried several browsers such as Edge, Chrome or Opera and I have the same problem in all of them.

I'm not sure I'm following you here. Are you saying you're unable to get games to show up at all or you're unable to click on them? If you could grab a screenshot, that would be helpful too.

How can I grab a screenshot in a post?

You can just upload it to Imgur (or your host of choice) and link to it. You can also embed images directly with @extimg(), just put the URL inside the parentheses.

thanks!

I upload the screenshot in Imgur. This is the link => https://imgur.com/Ndq5yH1

When the collection list is too long, it won't let me go down further and select any option below.
