The "Number of Days Rented" field is not visible in the mobile app, despite being correctly configured in Dynamics 365 (D365) as a Recommended field for the Car Rental expense category.

Steps Taken / Configuration Details:

• The field has been set as Recommended in the Expense Management configuration within D365.
• The issue appears to be isolated to this specific field.
• Other similarly configured fields, such as "Number of Nights" for the Hotel expense category, are displaying as expected in the mobile app.

Impact:

• Mobile users are unable to input the number of days rented for car rental expenses, potentially leading to incomplete or inaccurate expense reports.

Steps to Reproduce:

1. Navigate to:
2. Expense management > Setup > General > Expense fields visibility (Expense reports re-imagined)

⚠️ Ensure that the company you're configuring is the same company used to test in the mobile app.

1. Select Category:
2. On the left panel, choose Car rental category.
3. Field Configuration:

• Locate the field: "Number of days rented"
• Set the Visibility to "Recommended"
• We also tested with other values like "Required", but the issue persists.

1. Confirm Expense Category Type:
2. Navigate to:
3. Expense management > Setup > General > Expense categories

• Active category: Car Rental
• Inactive categories: 110-Sales-Car Rental, 210-Office-Car Rental
• For each, open the category and check the “Expense type” field.
• Value is set to “Car rental”

1. Mobile App Testing:

• Open the Expense Management mobile app
• Go to the Expenses tab
• Tap the "+" button to create a new expense
• Click Skip (no receipt needed)
• Select “Car rental” as the Expense category
• Enter a Transaction amount
• Leave or modify Currency, Transaction date, and Payment method
• Tap “Add more details”

1. Issue Observed:

• The field “Number of days rented” is not visible in the app
• That field appeared once exactly where I highlighted in yellow color

1. Validation:

• We confirmed the configuration is applied to the correct legal entity used in the app.

Additional Observation:

• This issue appears to be specific to the Car Rental category.
• For example, in the Hotel category, the field "Number of nights" is also set to "Recommended" and does appear in the mobile app as expected.
• Steps to confirm:
• Configure “Number of nights” for Hotel category in Expense fields visibility
• Create a Hotel expense in the mobile app
• Tap “Add more details”
• Field does appear correctly
