Even with Qty 2, $500 plans, my GPT 5.6 Sol Pro chats get throttled to medium in new chats only

So even with qty of 2, $500 plans shared, I go to use 5.6 Sol Pro and the button turns to medium. Anyone know why? Their webpage says this happens to $200 users with GPT 6, but says nothing about Max plans. I really really despise this company.

I just realized this morning that with any new chats started with 5.6 Sol Pro on the project home screen, the users model choice gets overode into GPT 6 Medium (the button itself turns to medium), but once inside the chat, the 5.6 Sol Pro model starts working after reselecting the 5.6 Sol Pro. The 5.6 Sol Pro model works in all my already existing chats as well. So there apparetnly is a glitch when starting new chats, it overides your choice and then you have to change it again once insdie the new chat?

THIS ONLY HAPPENED TO ONE OF MY PRO MAX ACOUNTS. — >. The other account did not have this issue… That account runs in incognito mode.
