How to solve issues with SharePoint calendar when using App in iPad?

Hello @SMarin, 

Thank you for reaching out to Microsoft Q&A Community.  

We're sincerely sorry for any inconvenience that this situation may have caused to you. 

To help troubleshooting this problem, we suggest you can try these guidelines to double-check and narrow down your issue step-by-step: 

• Using Web browser: use SharePoint calendar in browser like Edge in your iPad to see if it works properly. This helps isolate whether the issue is client-side 
• Check internet connection: ensure you have a strong and stable connection. Try switching between Wi-Fi and mobile data to see if that resolves the problem. 
• Update app or iOS: Make sure the SharePoint app and your iPad's operating system (iPadOS) are up to date.  
• Re-sign in your account: log out of your Microsoft account in the SharePoint app and then log back in. This can re-establish the connection and force a fresh sync. 
• Check permissions: make sure you're using the correct Microsoft account within the app and confirm with your SharePoint administrator that you have at least "Contribute" or "Edit" permissions to the calendar list. 

Please understand that our initial response does not always resolve the issue immediately. However, you can try workarounds and share with us more detailed information, we can work together to find a solution.      

Thank you for your understanding and corporation. Hope to hear from you soon.
