AMC+ Log in issues on some Roku devices
I signed up for AMC+ directly from AMC.com, started with a 7 day free trial, then automatically switched to monthly subscription thru AMC.com. Everything working as it should during trial period. After 7 days my credit card is charged for monthly sub as expected but unfortunately after the 7 day trial ended, was unable to log onto AMC+ app on various Roku devices. I am able to access AMC+ on my windows laptop, also able to access AMC+ on my smart phone and on my TV with Google TV Chromecast dongle and also access AMC+ thru my Philips Roku TV with RokuOS.
Also I am able to access AMC+ on one TV using a Roku Streaming Stick, but I have 4 other TVs with other Roku devices where I can not access or log in to AMC+, Two are Roku Express devices, plus one is a Roku Streambar and another is a different TV with another Roku Streaming Stick 4K.
I tried updating the latest Roku software and also checking for and updating the latest AMC+ app software; removing AMC+ app from roku devices in question then reinstalling, and resetting Roku devices and all combo of the above, including changing my associated log-in ID and passwords for AMC+. But still no luck in accessing AMC+ for those 4 roku devices, getting unauthorized request message. Contacted AMC+ support directly with no success, they basically tried resetting my AMC+ password, which had no effect for those 4 Roku devices.
I have also noted that, randomly on occasion the location of the AMC+ app in my Roku channel/app grid often times moves from where I have moved it to on the channel grid, (near the top 2-3 lines), it moves back to the bottom of the grid, when I turn off the Roku device & TV and then later turn TV with Roku device back on. This happens even on the one Roku Streaming stick where I can access AMC+.
Any advice would be helpful.
