Hi gisela ceresér kassick and thanks for your report. Could you also let us know the app ID of your application? The appID can be found from URL when your app is open in Composer. It would be also helpful to know which page/component in the page you are seeing the issue. Is this the issue with mobile preview or with the actual app built with the build service? If it is the latter case, then would be good to know the used build tag version.

BR, Timo Kapanen
