I think it’s positive that you had the thought of contributing and trying to watch the series through their platforms. I’m not sure it has been mentioned here but I’d suggest to hit their support channels as well, probably opening a request per individual issue you had (which are plenty).

I believe what others have said: Apple made it frustrating to use outside of their ecosystem to lure you in. Perhaps you’re lucky enough to draw the attention of some devs of the platform and they take pity.
