Image does not appear when installed on another phone

When starting the application, after installed in my cell, the images appear normal, but if I install the application on another cell phone the images do not appear. An application on local news where you use a second application to make news publications, this to appear texts and images I am using firebase storage, in the news application I am using firebase database to receive images.
I left the images at 30% high and full width.
I’m using the customlistview extension

which customlistview extension? and show your blocks maybe there’s something that causing the problem

deep host custom list

Show your airtable data… And what have you selected offline or online in custom listview extension… And one more thing i would suggest not to use this extension as there is no support

Instead use this extension to create your own listview
