Sorry for my late reply.
I was researching and contacting Brave Community to get information for you.
They inform me that Brave finishes perfectly for android, they are still developing full features for iOS.
To try to solve any inconvenience you have you can consult: https://community.brave.com/t/brave-browser-1-4-2-android-cannot-access-brave-rewards/90239/19
Good luck my dear friend.
Thanks for the lovely reply. I will try to install it on my PC.
I hope you have a great week ahead 💕❤️
