Actually had the same problem recently and I just had to call the office instead of trying to set up an appointment online
Right now u can't but if u need to register your vehicle they've doing drop off registration which means u drop off all paperwork filled out accordingly, specific to your situation and within 10 days they will call u back to pick it up and your good to go with registration. Most other things can b done online or unfortunately wait because they r definitely booked out 90 days. I got lucky my wife made appointment months ago and I piggy backed in with her. U too could solicit yourself at the dmv to someone with appointment maybe give them 20 bucks and piggy back with them. Meaning after they handle their business u handle yours just pay them to get through door with them. Hope this helps
