Hi, I have several hosted feature services that currently do not have GlobalID's on them. I know how to add the layers to Pro and add "regular" fields to them, but I can't figure out how to add a GlobalID to an existing layer. Thanks!
To clarify, Portal or AGOL? I don't have the answer, but I think it will depend on your platform.
You can add global Id to your feature class in PRO by connecting to SDE -> right click to feature class -> 'Manage' -> 'Add global IDs' and then republish/overwrite the services.
