@Michal Czaja Thanks for reaching out. The limitations mentioned in the Microsoft documentation are generally applicable to all instances of the V2 service tier (we introduced new sku's Basicv2 and standardv2) and not STV2. https://learn.microsoft.com/en-us/azure/api-management/v2-service-tiers-overview
Please refer: https://azure.microsoft.com/en-us/pricing/details/api-management/
Regarding the issue of workspaces, it was announced that workspaces will be deprecated in Azure API Management in June 2024. This feature was introduced in the Premium, Standard, and Developer tiers but after June 14th it will be only supported in Premium sku regardless of stv1/stv2 (versions of API Management's compute platform). please refer: https://learn.microsoft.com/en-us/azure/api-management/compute-infrastructure
If you're using workspaces in the Standard tier, upgrade to the Premium tier to continue using workspaces.
If you're using workspaces preview in the Developer tier, you can follow the steps mentioned in the document https://learn.microsoft.com/en-us/azure/api-management/breaking-changes/workspaces-breaking-changes-june-2024#developer-tier-customers
for any further information please refer: https://learn.microsoft.com/en-us/azure/api-management/breaking-changes/workspaces-breaking-changes-june-2024#developer-tier-customers
do let me know incase of further queries, I would be happy to assist you.
