Every time you use Browser, a session is created to manage your connection. Here is everything you need to know about how sessions work.
Each session lasts 4 hours from the time it is created or last extended. After 4 hours, the session expires automatically and you will need to launch Browser again.
Each creator can have up to 10 active sessions at a time. If you reach this limit, you will need to wait for an existing session to expire before launching a new one.
When you launch Browser, Substy automatically checks for an existing active session for that creator. If one is found, it is reused and its timer is reset to 4 hours — so you do not waste sessions by clicking Launch multiple times. A new session is only created when no active session exists.
If your session is about to expire and you want to keep working, simply re-launch Browser for the same creator. This automatically extends the existing session and resets the 4-hour timer from the current time.
Each session is limited to 300 requests per minute. Under normal browsing this limit is never reached. If you do hit it, you will see a rate limit error — just wait a moment and continue.
