Hi afernando,
Could you share more details on this issue?
How is your app created? Could you share a screenshot?
According to your description, I add a Date picker control on an app and locate it close to the border of the screen, the date can be selected without issues.
I also test it on a form, locate the Date picker control close to the screen border, I can submit the date to data source successfully.
Please show me more details to help reproduce this issue on my side.
Best regards,
Mabel Mao
