Upgrade your phone to latest OS you can and it should find it. I think it automatically blocks apps it knows wont work.

No idea why the link is down. Anyway, you can get it here :
mega.co.nz - org.getgems.messenger-1.apk
or
filedropper.com - org.getgems.messenger-1.apk

I downloaded v406 this morning. But after email conversation with daniel, I received v407 for testing attached to my email. So expect an update..

If you ask me that would be the worst timing ever to push an update and take down the download link.. The link being down pretty much kills the momentum All those referrals that went out today end up being a dead link.. its hard enough getting people to try something new so this does not help. Especially with no explanation from the developers.

Yeah, imagine that, such an unprofessional team, not working their asses on new year's eve.

/sarcasm off

Congrats to the team on their release. As an iOS user I am a bit disappointed we didn't get to it first, but as an investor I am happy to see the release and hear all the good news.
