Nextcloud app store not working

I installed NextCloud with snap on my laptop with Ubuntu 18.04.4 installed. Everything works very well, except the app store. When I get into Apps, I can see “Your apps”, “Active apps”, “Disabled apps”, “App bundles”, but I cannot see all others(“Customization”, “Files”, “Games”, …, “Flow”). System log does not show any report related to this… What should I do to fix it?

Thank you in advance.

Can you put the follow line in youre config:

'appstoreenabled' => true,

And do you use a adblocker?

Thank you for your comment! :slight_smile:

Well, when I put that line in the config.php, app store categories("Customization”, “Files”, “Games”, …, “Flow”) are not even displayed :frowning:

I do use adblocker in Google Chrome as an extension, but when I disabled it, nothing has been changed :frowning:

What else can I do? Thank you in advance.
