Wes, you provided excessive information. Who is "we", what is your location (internet in africa is different from internet in canada),
what is your computer (rpi3 is different from mac mini), what is your os (fedora-1 is different from centos-7), what
is your browser (netscape is different from google-chrome).

As to "what browser should work", on MacOS, google-chrome and firefox should be ok (that's what I test), on Linux,
stock firefox (usually an oldish esr version) should work, on el7 and ubuntu google-chrome works. On windows, google-chrome
and firefox should be ok. microsoft browsers probably not ok (no testing). cellphone browsers also not tested (but google-chrome and firefox 
should be ok).

K.O.
