IPad Pro calendar

Thanks for posting the screenshot! I believe I see the issue.

You’re not viewing the Calendar full screen.

Tap the three dots I circled at the top here and choose “Full Screen”.

And in that view you see only dots?

• Might you have changed some accessibility setting, perhaps related to character size?
• Might you be using an unusual account to house your calendar data? (My screenshot shows my iCloud calendar.)
• Would you consider providing a screenshot?

Are you using an iPad? Do you really have the monthly view set?
