Paying (a lot) to see Twitch ads?

So I'm a diamond member. That is supposed to give me some benefits for the not so small amount I pay every year.

Is it then normal that when I follow the the World Championsship (or others), I get a 30s purple screen blanking out the underlying Twitch feed every 10 minutes or so?  And if I click through to Twitch, besides the overloaded screen of uninteresting chats, I have to endure advertisment every so (too) often - this while having the privilege to pay $100 a year?

The subscription page clearly says No adds for the three plans. Not so, clearly.

Is there something I miss? Does chess.com have the same coverage somewhere without Twitch and its adds and nag screens?

Otherwise, I'll reduce my subscription to Gold.

Membership regards the Chess.com website.  Twitch is an entirely separate website with its own rules - including subscription rules under the Twitch platform.  Some advertisement rolls are controlled by the streamer (Chess.com staff) but some are also automated by Twitch itself without streamer input.

The purple screen you are getting is a result from using certain adblock or script blocking plugins.

If you don't want to see the ads, I personally recommend checking out the YouTube streams instead.

The stream on YouTube is at least cleaner, but the problem is the same: unless I have a subscription there, I'll have adds.

I'd expect that for the price of a diamond membership, one would at least have the Chess.com feed - it's their own production after all - directly (i.e. add-free), without Twitch or Youtube adds and crap. 

So if there is no other way, I'll save some bucks by downgrading, and save some € !!

Is there a place where this could be reported - possibly Chess.com is interested in knowing why people quit or reduced subscriptions. Or maybe not...

Update:

While downgrading my account to gold, it was downgraded *immediately*: this is dishonest because I *paid* for Diamond until 2022. The fair thing to do would have been to take note and have the level downgraded only *at renewal*, in this case in 2022.

I'm not unhappy to have downgraded, then: I really don't loose much, but I don't like businesses that are not really fair.

It acts as a credit when you downgrade but support can change it back and then you can change when you are ready.

As @UpbeatAngle posted, a downgrade just changed the level and you'll have gold for a longer time period. You can always switch yourself back to Diamond. If you want and try that and it looks like it's going to charge you more, you have support make the change instead as mentioned.

What you probably wanted to do was cancel the renewal. https://support.chess.com/article/585-how-does-membership-renewal-work

Streams used to be hosted on site, a while back, but they transitioned over to Twitch. There's no way for the site to honor a membership here on twitch
