@squid999 sorry about the late! Yes ads are gone and will be gone forever as long as we are still sponsoring it. We don’t have any plan to modify those instances so we will only make efforts maintaining them. We are still kind of short of hands but we will make sure instances will be upgraded to 4.x as soon as possible, luckily by the end of Q1 2023. Hope this clears out your confusions and thanks for all the questions! We will try our best to make it more transparent!
