On certain anonymous image boards I am unable to post using Brave as the Capcha will not respond at all despite seeming to load. Turning off the shield has no affect, nor does reloading the page.
This may be an issue with Strict Site Isolation. To test, go to
Settings --> Security --> Strict Site Isolation
Check to see if this option is enabled. If it is, disable it, restart the browser and try again. If this doesn’t solve the issue, let me know and we can try further troubleshooting.
This seems to have worked, thank you.
Happy to help!
