Hi, I made a misstake. We have some lightning pages related the opportunity object. And to separete the new pages from old pages/record type only for some profiles. I use the Assignments By App, Record Type, and Profile in the activate functionality for lightning pages. It worked, but when I need to do changes i recevies an error.the problem is that it can't be undone. The recomendation from Salesforce is to find the Metadata XML and it seems to be related to force-app/main/default/applications. We have several XML files because we have several apps depnding of the role in our company. in these XMLs I found a lot of ActionOverrides related to Laouts, record types and profiles: <profileActionOverrides><actionName>View</actionName><content>NEW_Opportunity_Layout_1_0</content><formFactor>Large</formFactor><pageOrSobjectType>Opportunity</pageOrSobjectType><recordType>Opportunity.kuga_sub__New</recordType><type>Flexipage</type><profile>B2BMA Integration User</profile></profileActionOverrides>My question here: should I only delete them all or is there a quicker better way to do this?
