Hello Team - please advise regarding the below scenario.

Scenario:

1. Org has an Approval Process on Lead object
2. The FINAL APPROVAL Action is to Lock the Lead
3. In Classic everyone can clearly see that the Lead is Locked
4. In Lightning there is no visibility that the Lead is Locked and so, when the User later attempts to Convert the Lead, they simply get a nondescript "Invalid Cross Id" error
