MSC's website is SO BAD!

Does anyone have a trick to navigate this piece of crap?? I was finally able to sign in by using Chrome or Edge (couldn't get in on Firefox) but still can't see anything but the stuff they want you to buy: excursions, dining, etc. I finally had to call the MSC number and get an agent to do the e-check in for me. I've spent way too much time trying to use it. Ugh, I hate this thing SO MUCH!
