I've updated to the latest version and hoped this would include improvements to the IPTV topic.
I enabled IPTV in the services of the last Omada Controller Software - Bridge Mode, WAN (for Telekom),
but after 10 seconds it starts stuttering again and the MediaReceiver loses connection.
This version worked perfect: https://community.tp-link.com/en/business/forum/topic/514528
@Fae Are these changes from version 1.1.1 beta in the the version 1.2.0 also implemented?
