@rvdborgt  you have more experience with useing the mobile pass :)

What do you mean by "My Pass says the days are free”? Do you have a screenshot?

Do note that just removing a journey from My Pass does not deactivate/cancel a travel day. To cancel a travel day, go to My Pass, select the travel day and then tap on "Cancel travel day”.

It's best not to activate travel days in advance. If you postpone plans and forget to cancel your travel day, then you loose it.

Many thanks for your elements. Here are the screenshots

Seems like I have only removed and not cancelled ?

Just be successfull with the cancellation ! Got back my two days, thanks a lot !!!!
