Have not received lease agreement despite approval (FL)

Yesterday I was approved at an apartment complex and was told I would recieve a lease agreement. Yesterday upon checking my rentcafe portal I noticed the lease summary button/section became available as well as my move in date, but the “lease creation” section where I assume you actually sign just loads a blank page, even on multiple devices. I have not received one in my email inbox either. I have a move in date of Tuesday, and I believe they will be closed Monday so I cannot afford this to cause a delay as I have a job offer. What would happen if I show up on move in date without having signed agreement? Have they not sent the agreement? Is there a technical rentcafe glitch? The office is supposedly open today but my calls and emails and attempt to contact have been unsuccessful. I unfortunately can’t visit in person as I am over 3 hours away. Input would be appreciated.
