Is there anything I can do to reduce the long pause I get when authenticating a voucher on the portal.

After connecting to the OPEN ssid it seems to take a long time to redirect me

On one of the phones I have... I have to click a message to redirect... on another I am automatically taken to the voucher authentication page.

And then once the voucher code has been correctly entered it takes a long time to confirm it is a success and release me... takes me off to www.msftconnecttest.com ... but sometimes it just hangs there waiting... is there a way to change that to google or something?

Not sure why it's so slow - perhaps I need to configure something on the pc running the Omada Controller???
