Background banner image for employee center portal is not being updated for mobile viewDescriptionWhen the background banner image of Employee Center homepage is customised, the changes get reflected properly in the desktop view, but when switched to mobile view or tablet view, the changes are not reflected and the banner image switches back to the default background image.Steps to Reproduce 1. Navigate to https://[instance-name].service-now.com/sp_container.do?sys_id=6791a66b532030101865ddeeff7b1236&sysparm_view=sp_instance_config&sysparm_record_scope=4249e63a28d54d61bb6fbf61fd86cccb&sysparm_nostack=true2. Click the 'Manage Attachments' link present on top of the form.3. Remove OOB "Mobile_800x250.svg" file attachment.4. Upload any .svg image.5. Go to https://[instance-name].service-now.com/esc6. View the page through the mobile screen, for example, iPhone 12 Pro.7. Observe the background image uploaded on step 4 does not appear behind the search bar.WorkaroundNote: By design, we are hard coding mobile banners from a css property in "ec_dashboard" page. A detailed explanation to update the mobile banner is below: 1. Navigate to the "Employee Center Homepage - Container 1" record with the following URLhttps://[instance-name].service-now.com/sp_container.do?sys_id=6791a66b532030101865ddeeff7b1236&sysparm_view=sp_instance_config&sysparm_record_scope=4249e63a28d54d61bb6fbf61fd86cccb&sysparm_nostack=true 2. Upload the image by clicking on the 'Manage Attachments' link on the form.3. We need to get sys_id of the uploaded attachment in step 2, either we can get it by copying its link address and extracting the sys_id of the attachment, or we can go into sys_attachment.list and find sys_id of the uploaded file. 4. Navigate to ec_dashboard page record with the following URL https://[instance-name].service-now.com/now/nav/ui/classic/params/target/sp_page.do%3Fsys_id%3D8c51a66b532030101865ddeeff7b120d%26sysparm_view%3D%26sysparm_domain%3Dnull%26sysparm_domain_scope%3Dnull%26sysparm_record_row%3D1%26sysparm_record_rows%3D1%26sysparm_record_list%3DidCONTAINSec_dash 5. In the field "Page Specific CSS", replace the sys_id present in "$banner-768-svg" variable with the sys_id retrieved from step 3 and save the changes. Now the banner should appear on mobile view/devices.Related Problem: PRB1557181
