Overwatch 2 game pass not connected

I have owned and am paying for the xbox game pass ultimate (£12.99-£14.99 per month) for awhile and I mostly got it for overwatch 2, however I found out recently that for some reason I’m now not connected anymore (I haven’t used a different account or xbox so I’m not sure what’s happened)…I have both my battle.net and xbox account connected (and my xbox game pass is showing as active) but it just isn’t working for me…could anyone help???
