Breadcrumbs report gradually down after 6 Nov 2020. Even no additional changes are occurred from my side and not found any recent update from google about breadcrumbs. And site links search box also down.
Let me know why breadcrumbs and search box links graph down.
Note: I Implemented schema by adding a custom field in the site and used and not use any plugin from mid of September. At the start everything gonna ok but after 6 November I'm facing the issue.
