Great job jabronis - attached picture is what the site looks like on an old phone. All the buttons are broken and do nothing, except for the Modlog which somehow is still accessible. Tried different browsers on the phone, tried clearing all the cookies and cache, still doesn't work.
EDIT: This came off a bit hot and aggro - it just sucks since pre-migration the site worked fine on my dinosaur phone, so I'm pretty frustrated. Makes me appreciate communist web-design (like marxists.org and redsails.org) even more.
Memmy works on some older devices, like iOS13/14 and is updating frequently, though still limited functionality. Mlem requires iOS16 since v2 so it's stuck not working on my phone, and the beta is closed anyway. Memmy's beta might still be open to try. Logging in and viewing has been working but images and upbears were borked last I tried on the phone but it's getting regular updates to fix functionality so might eventually help closer to an actual release.
