The users are seeing the error "The reference to entity "sysparm_stack" must end with the ';' delimiter" when openining links in mobile.Issue The users would see the error "The reference to entity "sysparm_stack" must end with the ';' delimiter" when they try to open URLs in emails. Ideally, the users should be redirected to the records that they are trying to open from email links. On desktop browsers, this works without issue. But in mobile browsers (both Android and iOS), when users click on the link, the mobile browsers report the error from ServiceNow.ReleaseMobileCauseThe probable cause of the issue is that the system property 'glide.ui.escape_all_script' is set to false in the affected instance. ResolutionSetting this property with the value 'true' will fix the issue which is the recommended value as per the below documentation.https://docs.servicenow.com/bundle/rome-platform-administration/page/administer/security/reference/r_GeneralSecuritySettings.html https://docs.servicenow.com/bundle/rome-platform-administration/page/administer/security/reference/escape-jelly.html -->Go to sys_properties.LIST table -->Seach for property with name 'glide.ui.escape_all_script' -->Set the value to true.
