Hello,   I have an organization consisting of multiple networks(use WPA2-Enterprise with Meraki RADIUS for wireless LAN authentication). When new users are added to the organization, I use Meraki dashboard API to register them as merakiAuthUser in multiple networks. Previously, it worked well with the following steps: Register the user through the Create Network Meraki Auth User API for Network 1 Update the user through the Update Network Meraki Auth User API for Network 2 (and beyond)   However, since the update in May (we noticed the issue a few days ago, but it may have been occurring for longer), the following error occurs when updating the user in step 2:   HTTP Status Code: 404 Response Body: {"errors":["User with ID <user-id> not found"]}   If I try to register the user with the same email address for Network 2 with create user api, I get the following error:   HTTP Status Code: 400 Response Body: {"errors":["Email has already been taken"]}   What should I do to register a guest user as merakiAuthUsers to multiple networks?   Many thanks in advance for a response   Seiro ...
