Can't see events saved to calendar as the first Admin

I just discovered, by accident, that the events are being created online for the first Admin but for some reason they are not showing on the browser at https://[MYDOMAIN]/cloud/index.php/apps/calendar.

I’ve tested using Chrome and MS Edge.

All other users can see their events created with the web browser, except the first Admin.

I discovered this after configuring the email on android as an exchange account. To my surprise all the test events started to show up.

All I need now is to figure out how to see my events online. Funny, because I’ve the Admin account and it works for everybody but me.

Can someone reproduce this?
