HELP!!!! Multiple issues with my Roku 4K+ Model RC608 remote and channel access.

I have multiples of this remote set up on several of my TV's and they were all working fine for a few weeks then all of the remote voice controls stopped working along with their "back" or "return" functions. Also, I cannot access my ESPN+ subscription on any of them. It says it it disabled and won't allow a activation ;code to be generated. ESPN says it all looks good on their end. I can access it on my computer, but not on any of my Roku remote setups on any of my TVs. I have tried everything. Unplugging my modem, router, Roku, removing remote batteries, repairing, updating channels and Roku, system restarts, back to factory settings, changing out batteries..............everything. Nothing has worked. I am at a complete loss.
