I keep Brave up to date always and have been having the same problem for a while now on both windows and android using Nightly and the standard browser, but its far worse on android. I also noticed when the news feed doesn’t load the BAT triangle menu is not responsive either. Currently I find if I close all pages, then relaunch the browser it usually fixes it (but not always -sometimes have to give it a couple of goes). It’s a bit of an annoyance but I thought it might just be me, so hadn’t reported it.
On Android:
Brave 1.51.121, Chromium 113.0.5672.163
Android 13; Build/TP1A.220624.014
*It works periodically but not all the time. I don’t know what triggers “buffering”. When I open a tab, the page would load but most of the time it doesn’t load/show the page correctly.
My issues are on Windows (Nightly and regular Brave browser) and on android (android nightly and regular brave). I confess I am not sure what you mean by release?
I knew of the different browsers yes but was confused by the term ‘release’. So at least I can confirm now I have the problem on both release and nightly, both versions installed on 2 x windows, and 1 x android devices.
I’ve experienced similar problems (infinite loading loop and empty Brave News page) to the ones described in the original post. I am also using an Android 13 phone and Brave is on version 1.52.122
Although I cannot provide a solution to this problem, I have found a workaround that makes it usable again: Settings → Brave Shields & privacy → section: Clear browsing data → option: Clear browsing data → time range: All time
Would be interested to see if this also works for others.
