@piotr-iohk I think this needs to wait for the toast to hide:

[0-0] Error in "@settings - Settings.Security and Privacy.@settings_06 - Can swipe to hide balance"
Error: element ("~DrawerSettings") still not displayed after 30000ms

@pwltr there seems to be an issue introduced. "Hide balance on open" setting is not preserved.

Hmm, works for me. Could be related to this: #246 I don't think it is caused by this PR. If you can please retest on master branch.

I can see it on master too indeed. Strange that it passed through e2e as one of the tests @settings_06 has this particular check and it is pretty much 100% reproducible for me. Anyway, I will create a bug ticket and disable this check in the test until the issue is addressed.
