I uninstalled today Brave from my HiSense E30 which has Android 9 because I noted a minor glitch in the start page (something related to the position of the favorites sites on the screen) but when I tried to recover Brave from the Play Store a message tells me that Brave can’t be installed on your device anymore. 
So somebody can give me a safe link to download the last version of Brave browser compatible with Android 9? Please 
I could be wrong, but it appears 1.80.126 is the last that targets Android 9+.
As for where to download it, Brave’s Github page has a lot of their APK’s, but I actually couldn’t find this one, however APKMirror does host it.
I don’t wish to link however to unofficial mirrors per their insistence on using the official Github repo, but since I couldn’t find it, I’ll at least screenshot it. How you obtain it is up to you unless @Mattches has a direct URL for the best Android 9 compatible APK he might prefer you use than the one I found.
Personally my big thing is this, it won’t have the latest security updates, and Android 9 itself will have less, so do keep that in mind.
(Sorry Mattches for tagging you a lot, I don’t know much of the others and you seem to be better on navigating Github than I which would benefit this user.)
Well we typically recommend not running outdated versions of any browser for the sake of security. That said, if you do wish to do this you can get the relevant .apk file from our Github releases page:
