I have a subscription in the US and have been watching Picard and Lower Decks -- the few ads I get are their up front spam promoting other shows (I hit reload and the 'forced' up front ad switches to the CBS logo and plays in a couple of secs). Another show I watch has a few ads, I think the are trying to see how much they can get away with before people cancel. I bought a year at 1/2 price and I won't be reupping, its a pretty low value and quality streaming service on all fronts (ads, content, video quality, app/site navigation and player, absolutely no useful technical support if their player or service is glitching, cable company class customer avoidance policies and systems).
The video quality on easynews is also much better should I want to watch more star trek in the future.
Have they finally allowed you to set the alert sound in IOS? My problem with mobile discord is the feeble little ding they deem you are allowed to hear is so quiet even with the phone turned up I don't hear alerts. There are several complaints in their bugtracker about this going back 7+ years, they seem to want people to miss alerts for some marketing/profit reason.
On other platforms you can overwrite the sound file in the package with a proper alert, but not with the "we're apple, fu and enjoy it" IOS stuff.
