Using the Brave Beta from the Google Android Store.
I’ve got Brave nightly on my Windows PC.
( Version 1.12.61 Chromium: 83.0.4103.116 (Official Build) nightly (64-bit))
I tried the Sync on the Android and after I enter the 24 words I tap on confirm. It does nothing. It’s like it doesn’t respond. I rechecked the words are correct.
Brave beta 1.10.99 (Chromium 83.0.4103.116)
Android 10 SM-G90F build/QP1A 190711.020
