Describe the bug

When creating an appointment with a time span of more than 7 days, the error message just says "Please check your data".

Environment:

• Device model: Huawei P10 Lite
• OS version: Android 8.0.0
• App version: 10.3.0

The error message should be updated. As it is completely useless to limit events to 7 days, we should remove this limit.
