@Julie713,
Thank you for reaching out to us.
I believe this is likely due to Brave’s Shields — can you please try going to eventbrite.com (same page you show in your recording) and disabling Shields for the site by clicking the lion icon in the address bar and turning the main toggle “off”. The page should refresh automatically. Try clicking Browse again to insert an image.
If this does not work, you may also need to disable Shields in the first pop-up window that does appear (using the same method listed above).
I think this the chrome popup blocker, if you click on the icon in the urlbar (next to the magnifying glass) it should give you options to allow it. @Julie713
Thank you for mentioning this solution. Strangely enough, when I went to Chrome to test it, the only icons in the URL bar next to the magnifying glass were Share and Bookmark. The pop-up was fully active when I tested. Go figure! But good to know for the future.
