Hi Isaac,

Based on the details provided, we have analyzed the query and confirmed that the SfScheduler. It is working as expected at our end with the latest NuGet Version 33.1.44.

For reference, we have attached the tested sample along with the output. We would appreciate any additional information, especially regarding the scenarios where you face this issue and if possible, could you kindly replicate the problem with our sample along with replication video.  Also, could you kindly confirm whether you have MAUI SfScheduler in the sample.

Additionally, we kindly request you to share the following details:

• Issue Output

• MAUI Controls version

• Device version (iOS, Android, and Windows SDK)

• .NET version

This information would be extremely helpful for us to investigate further and ensure a comprehensive resolution.
Regards,
Hadaya Rahman M
