Prisma SD-WAN sites cannot connect to Prisma Access - Error "Inner ip pool usage reach limitation and need update"

[NevinN]

We are getting an error when going to any branch site and try to connect to Prisma Access.

The error states "Inner ip pool usage reach limitation and need update"

We have added an additional subnet and still the issue remains.

This is under Manage -> Prisma SD-WAN -> Resources -> SASE Connectivity. In that page it's under "Branch Sites" and "Tunnel Inner IP Pool"
