Housing Confusion????

My roommate and I both put down a deposit on October. Although I had to change my term from Fall to Summer B, I signed a Summer B-Fall-Spring housing agreement in February. When I’ve gone on my portal for the past few months, all I’ve seen is a notification that assignments will come out mid May.

This morning when I checked I no longer saw this screen, I saw a waitlist page. That said I could join waitlist by proceeding to the next page with no option to do this. I also saw an option for Summer housing (which I swear on my life was not there before) with an unsigned Summer B contract. Do I need to sign this in addition to my completed Summer B-Fall-Spring contract? Why did the waitlist just now show with no option to join?

Any help is appreciated I’m panicking
