If you need some time off from the platform, it's very easy to pause your submissions and avoid letting artists wait for feedback that won't come. It's simple: go to “Settings", click on “Availability”, untick the box, and save.
When you wish to reactivate your submissions you have 2 options:
Log in to your profile > go to “Settings" > “Availability” > tick the box and save it
Otherwise, if you log in, you can simply click on the pop-up that will appear on your screen asking if you would like to continue receiving submissions.
