- System Administrator Profile with Convert Leads, and full access to accounts/contacts/opportunities
On the classic page I can see the "Convert" button and it opens the lead conversion page, where I can convert a lead. In lightning I cannot see the convert button. When I move the sales process to the Converted status at the end, it does not give me the full conversion page and I get an alert indicating that the lead is not converted.
This is in a sandbox, in production (same lead, same account) I can convert using either method. I don't see any difference in settings.
