Dear @jiawoo,

Thank you for posting the problems on the TP-Link Community!

1) http & https redirect not working after upgrade. Example : http://www.facebook.com is work. anthying behind /XXXXXX will not  work . Example : http://www.facebook.com/bacfe/..... not work

This issue has been discussed in other threads, it will be supported in the next version, please wait for the new version patiently.

2) Advertising Page not working. I try to attachment with Picture but result faile , I has try so many picture format and size also not work.

Are you setting this from the cloud access (https://omada.tplinkcloud.com) and getting the error message "invalid parameters"?

If yes, please locally access the Controller via its IP address to configure it. The issue will be fixed in the next version as well.

3) Can New firmware control LAN user also can be Login with Portal? if yes, how to do or any additional hardware ?

Yes and the Omada Router is required (coming soon).

Portal authentication takes effect on SSIDs and LAN networks. Omada EAPs authenticate wireless clients which connect to the SSID with Portal configured, and the Omada Router authenticates wired clients which connect to the network with Portal configured.
