For some reason the okta.js library is sporadically calling the getWithRedirect method in the JS file of the same name, which performs a window.location.assign() which is triggering a browser:unload event as a result. There seems to be no actual pattern, doesn’t appear to be in line with the expiration time on the token nor the expiryEarlySeconds value in the initial config object.
And then when this happens, the token does not renew in the background. Is this common?
