AMC Plus subscription not showing on the app

You literally WOULD NOT believe the insane problems & issues I've had w/ this nutcase app, Roku & AMC+ ... We're talking just trying to stream content like a normal person after buying a premium AMC+ yearly subscription from Roku, & not in the Roku channel app, just thru a Roku device with Roku as the payment intermediary. Just wanted to have it on both my Sammy smart TV & as a standalone app in my Roku device. Only wanted it in both places because the clarity of the upscaling UHD picture on my wired TV was miles above the picture than it was with Roku's wifi connection. But they'd repeatedly force me to re-login, again & again, & also require I login using the same payment form from last Oct (who remembers that $#!+ when it was from last year?) & so when I got it incorrect? Repeatedly charged me for brand new, full yearly subscriptions each time I used the wrong credentials! It was like, dude! Seriously? SURPRISE! That's nearly a C note each time! & their response time for each one of these support requests? I think the Whitehouse, the Pentagon, & the IRS together probly respond quicker than these dudes! It's straight outta nightmare land, or maybe from one of their Shudder horror films, dealing with these moronic situations. From a business perspective? It makes no sense whatever, & seems more like a scam, or maybe they purposely want it to fail. IDK. To boot, I think their people skills are nil & border on snotty & vindictive, probly from all the similarly POed patrons they've royally screwed w/ this defunct system of theirs. Hope you had better luck somehow. God forbid people want to stream AMC Plus in two places with their one subscription! THEY WILL MAKE YOUR PAY DEARLY! And somehow turn it all around on you and make it all your fault. Crazy, huh?
