To start off, I exclusively post from a Galaxy S9 using the Chrome browser. Lately I've been having issues with the buttons on the bottom of the screen not doing anything when I click on them, as if they didn't exist at all. The menu buttons, and the post button are all included in this. The header buttons are fine, though. Is it just me, or something with the site? I know it's not exactly optimized for mobile use, but I have never had as much of an issue as I have lately.

Although this is a different issue, jase's answer would still apply.  It's also worth noting that recent changes to Chrome have caused issues with this site, and many others (like Chrome suddenly deciding that the internet standard for handling cookies should be changed).

Not to sound rude, but is there anything being done to try to figure out all these mobile problems or correct them? If there was a mobile testing page (sort of like the beta, but specifically for mobile), I would gladly throw my hat into participation to help if I can.

You mean like http://responsive.rpol.net/ ?  Also http://beta.rpol.net/ itself.

Not specifically for mobiles, but for a whole new site design which should be more mobile friendly.  See also: link to a message in another game

So yes, plenty is being done to fix the issues, as jase's busy schedule allows.  Issues with browsers that don't comply with internet standards are, however, a different matter.
