If you can't publish a collection, you may have reached the active collections limit. To know more about active collections, check: What Are Active Collections?
You can check the limit in My Collections section.
There isn't a limit of collections you can create, but there's a limit of active collections you can have at the same time. The active collections limit depends on your rank in Streamloots.
- The Streamer rank can have up to 2 active collections.
- The Affiliate rank can have up to 3 active collections.
- The Partner rank can have up to 7 active collections at the same time.
