Can you please tell me what mobile app version you are on? You can find this information by going to account > about and the version will be at the top of the page.
If your app is not up to date, please make sure to update it then check if the issue still persists.
Thanks for the context! I believe the latest version is 2.56.0. Can you please check if you are fully updated? If there is an update, download that and try to reproduce the issue again.
