meetings disappearing from my iPad

[okays]

I have meetings listed on my iPad, laptop, and phone.  All of a sudden, two days ago the bulk of the meetings disappeared from my iPad.  I got the idea from here that my calendar synchs were disabled so I did my best to fix that.  Still, most of my meetings have disappeared. Don't know what to do now.  I've always loved zoom but this is really affecting my business and I'm very unhappy.  Apparently, I'm not able to access a live tech support person with my level of subscription...which is really a ripoff.. Considering moving to another platform
