I still use rif. You can get the app as an apk, and patch it to replace the original API key with your own using something like vanced. I already had my key from before the debacle, not sure how you get one these days. Anyway, it did give me some trouble while logging in, but eventually it worked.
Which part broke exactly? Because I can confirm the one on my tablet, which I installed a long time ago, still works. Haven't installed it on my current phone which I got not too long ago, so I'm wondering if it's gonna be a problem.
