Not wanting to ruin your sales or anything but, if you head over to
https://www.massplanner.com/, you can see that their service has been terminated. That's if OP is selling this particular software.
Indeed, instagram terminated the service, but the bot is still very much functional. So if there's people who still want it or wanted it but couldnt afford it before it actually got shut down, hit me up since I can hook you up with it. You will have it 100%, no monthly plans anymore and you wont be tied to any licenses.
I would not say I nulled it since the service itself got shut down and its not hurting anyone, so why let this amazing software go to waste!
