@GeetaSarvadnya can you reproduce this every time on a clean profile? I tried reproducing the above on the following platforms:

• Win 10 x64 VM using 0.60.26 Chromium: 72.0.3626.96 - Couldn't reproduce
• macOS 10.14.2 x64 using 0.60.26 Chromium: 72.0.3626.96 - Couldn't reproduce
• Win 10 x64 (psychical machine) using 0.60.26 Chromium: 72.0.3626.96 - Couldn't reproduce

For the above, I launched brave using a new profile and ensured that Allow contribution to videos was enabled by default when enabling Rewards via the Rewards panel and through brave://rewards.

@kjozwiak I am able to reproduce the issue on 0.60.26 Continuously. This issue is happening due to delay in loading the page objects. If i keep open the auto contribute settings page and visit other pages, issues gets resolved automatically.

Released version: 0.59.35 - No performance degrade

But, on release version this delay is not there. I guess there is some performance degrade on 0.60.26

[NejcZdovc]

I think something else is going, don't think it's related to performance

STR seem easy enough but I haven't ran into the above on a VM nor my psychical machine. Wonder what the difference between @GeetaSarvadnya's machine/STR and mine are.

@LaurenWags can you see if you can reproduce this when you have some time?
