Auth kicking out

This could be a normal behavior but feels weird. Please let me know if I can ignore. I can demo this app with Chrome and Safari so this won't happen in front of the stakeholders.

I have 2 pages. Campaign page (get-campaigns) need auth. Upload page (get-campaign-by-token) does not need auth. Both pages are opened in Safari in different tabs. If I switch between tabs I am getting logged out. After writing this it sounds normal? Does it?

Here is the log:
