On iPad and iPhone the "full screen" button is not present.
IOS does not support a full screen mode, unless you add the link of your site to the home screen, more info here.
* On Chrome on PC and Android the "full screen" button is present and works fine on the "root" album of an "album of albums" but not on one of the linked albums
I did test this with the PhotoSwipe sample album which is an album of albums. It works fine at my place with Windows 10. but of course you should set in the Viewer settings 'Use full screen for a picture' = Yes, see enclosed screen-shot ViewerSettings.PNG
* In Firefox and IE on PC, the "full screen" is present but has no effect in either root album of an "album of albums" or a linked album.
I did test this with the latest version of FireFox, Internet Explorer and Edge on Windows 10 but I see no problems, it works fine on my PC.
It seems that this feature is something that is highly dependant on what browser is being used.
The Full Screen API used by plugin screenfull.min.js is supported by all operating systems except iOS.
I have found another posting which talks about a guide about 'full screen images' by rotating the iPhone to portrait, then landscape but I have failed to find the guide. Is it available somewhere?
To get a complete full screen display of your album in iOS, turn your iPhone first in portrait orientation and next back in landscape orientation: the bottom tool-bar and the Host domain bar will both disappear, leaving it in complete full screen mode. The tool-bar and full URL bar will appear again when you tap on top or bottom of the page. Unfortunately you have to do that under iOS to use the buttons on top and bottom of a page!
So I don't know why you get different results, please give the link to your site, so that I can investigate it in your albums.
I think that the "album of albums" flag had managed to get unset somehow or other. That is now fixed and the links work as they should.
Clicking a link on the root page now take you direct to the respective album.
No Chris, you should not use that iframe.
Look at the attached screenshots how this looks on an iPad. The index page has no link back to the top album and a slide page looks ugli.
The example album looks much better I think.
If you insist to use an embeded album, do it in that case in a responsieve way as you can see here

You still use an album of albums, which is absolute not required if the underlying albums are all made with the same skin!
Making an album of folders is easier and gives automatically better navigation possibilities.
The fullscreen problem on desktops is an easy one. The Firefox developer's console even puts out a plain-text message that identifies the problem. For Edge, IE11, and Firefox, the iframe tag needs the allowfullscreen attribute:
