I am working on creating a Lightning Community. There's this My Account page where a logged in community user can view & update the Account Record information attached with their User Profile such as Account Name, Phone Number, Address, etc. When community user edits and saves the account, everything works fine except for the account page layout in the community. I have setup a specific account page layout for Account for community users, This Lightning Record Page has only one region with Account details, no Related list and no Chatter feeds. But as soon as I edit and save the account info, the page layout changes and starts displaying the related page tab and chatter feed tab. and the url of the page also changes from /my-account to /details/[sfdc-id]
At this point I have checked everything in Community Experience Builder & Salesforce Lightning Page Layout Assignments but I can't figure out this issue. Can someone explain what might be going on here? Any help is appreciated.
