Cannot schedule a meeting from the app

I have the same problem on my free account, but no problem on my pro account.

Interesting that it's on your free account but not the pro. I don't have a pro account so can't test that on my end.

Sign in to the Zoom desktop client.
On the Home tab, click Schedule .
This will open the scheduler window.
Select your meeting settings. Note that some of these options might not be available if they were disabled and locked to the off position at the account or group level.
Topic: Enter a topic or name for your meeting.
Date & Time:
Start: Select a date and time for your meeting, but remember you can start your meeting at any time before the scheduled time. You can also manually enter any time. For example, you can enter 15 in the minutes field.
Time Zone: By default, Zoom will use your computer's time zone. Click the drop-down menu to select a different time zone.
Recurring meeting: Choose if you would like a recurring meeting (the meeting ID will remain the same for each session).

I have the same issue - just a blank page.

I can no longer schedule a meeting from my iPhone, but I can from my desktop, so I think it's a problem with the iOS.

Zoom app is updated. Pro account! This is a PITA!

I have the same issue.  We have a recurring weekly meeting.  I always test the zoom link on our weekly email before I send it via MailChimp.  It always works.  Tonight, it shows a blank page and a red X with the message "Invalid meeting ID."  What's going on?

You can still schedule a meeting from the Zoom clients the format of the interface may have been updated. Otherwise there are Zoom apps like Salepager that let you schedule Zoom meetings and send the link or you could use your email calendar.
