Blue Iris

I'm running the latest version of BI 5, which is 5.7.9.1.
When I view the cameras in my browser using UI3, the timeline is not available. I click on an earlier time to view one of the cameras, and nothing shows. When I open it in the software, I have no issue. So, it appears to be a UI3 issue.

I can only tell you that it is working in UI3 here with v5.7.9.1 in Win11 Chrome browser. Are you able to try a different browser, or look on a different device ?

It's now showing up. Strange.
But, I do have a good amount of dead spots where no video was recorded from any of my 9 cameras. But, that's a BI issue, not UI3.
