Online Banking login issue

Description of the issue:
I cannot login in my banking account (website) on brave. After confirm the login with the app and then switch back to the browser nothing happens. It only stays on the Site where i ask to confirm the login

How can this issue be reproduced?

  1. I tryd 2 banks and tryd to logged in with my Account(ing+commerzbank in germany)

  2. I switched to the App(s) and Confirm the login. Then the apps shows confirmed i can back to the browser

  3. In the browser nothing happens.

Expected result:
I tested both Apps on Firefox. With this Browser all works. Also confirm login with App, then switch to Firefox and automaticly the website forward me.

But with brave it always stuck at the site where i must confirm.
I also tryd disable/enable security features but all not work (enable cookies, disable blockers…) i tested every setting but no one resolved the Problem

Brave Version( check About Brave):
1.77.101
Mobile Device details
Galaxy S24 Ultra
Additional Information:

Anyone have the same Problem or an Idea?

Does it work on desktop?

Yes, no problem with Brave on desktop. Only on my mobile browser does the problem exist.

I checked the desktop w/mobile UA, same trackers are seen on both mobile and desktop. So I don’t think its that? Maybe fingerprinting issue? from a non-user, its impossible to check this tbh.

I’ve tested the nighly version without touch any settings and there is the same issue.

  1. open Firefox, login in online banking website + confirm tan via app = forward login work

  2. open brave, login in online banking website + confirm = nothing happens after switch back to brave (nightly the same). Also disabled brave privacy doestn fix this too

Does desktop mode in android work? Which site exactly, I could ask if anyone else can repro.

No, in Desktop mode is the same.

The websites are ing.de / and commerzbank.de.

Both required confirmation via tan / ap

Edit:

I tried logging in via browser and using my tablet to confirm the login…then it worked. Sounds like there is an issue switching to the banking app and back, or something

Edit2:

Brave had a “restricted” battery setting on my phone; after changing it to unrestricted, the login worked. That’s strange, because Firefox was also restricted the whole time, and there was no issue.
