mobile view has no link to get past the first 20 sub-albums / sub-folders

[patman-cp]

Piwigo version 14.2.0 but this was happening with earlier versions too.

In mobile view, if only sub-albums / sub-folders are visible only the first 20 of them are shown, and I don't see any way to see any more: there is no "next" link or numbers at the bottom of the page, like the desktop view or a page with only images has.

I see this same behavior in both Firefox and Chrome.
