Hi, we have recently the same issue.
https://vod.pl
This is very painful for us, as we use same application for playing DRM content across different browsers and we use DASH on part of them and HLS on Safari.
If user-agent is wrong we have issues to play correct stream and DRM (widevine vs FairPlay) on Safari.
I would appreciate any help related to how remove https://vod.pl form lists of domains that Safari uses to enable site-specific hacks.
