I kinda have the same experience, especially on weekends
for me, the DAZN channels are effected 99% of the time. if the game is popular/in demand, it starts lagging and/or I cant even access the channel
it affects dazn 1 (never accessible for me), dazn 2 (lagging), dazn bar 1 (lagging) and dazn bar 2 (lagging).
somehow all the other channels (for instance sky sports, prime live) work just fine. if it wasnt for dazn, I would give my rapid fire IPTV a 10 out of 10, but because dazn was the main reason I even got into iptv, I currently just can give it a 6/10
i am in touch with my reseller currently and he is trying to help, I really hope we can resolve the issue, as it really worsens my iptv experience
