Opportunity Entity - No view selection

Hello all,

while Opportunity is enabled for mobile and tablet access, when we try to select another view than the preselected one this is not possible.

The bar with the selections is shown but no option is available as shown in the picture below. Does anyone know anything about this?

Note that for all active entities for mobile - which have the same details like opportunity entity in settings - we can select the different views.

Thank you in advance,

Alexandros
