On mobile devices, the current breadcrumb collapses to hide everything except the last element anyway. That should be possible to convert to AMP but not useful so we left it out. The menu likely won't work. Or it must be very basic.
It would be nice to come up with some kind of navigation. Also, any reason why the separate pages of threads are not amp compatible? How about the individual forums themselves?
Currently only the first page of a thread has amp support. The reason is user should go to full page after the first preview (amp version) in Google. Technically it can be enabled for every page though.
BamaStangGuy @xfrocks We have pages indexed in google that are not the first page. I am ok with leaving the navigation on the page normal but there should be an amp page for every page of a thread because those are still indexed.
