1. The profile picture in the link, can it be a custom photo that I upload? Or it must be a bitmoji? https://lensstudio.snapchat.com/creator/3wSvCwFQzAXcUCE6uZQPVg
2. I have some lens with high number of views, and the views still increase every day. When I create an improved lens, shall I update the improved lens to the existing lens with high number of views, so it would be viewed more? Then, submit the old lens again, so people view the old lens if they want?
Or I should keep the old lens, and submit the improved lens as new lens and pray that it become a lens with high views?
3. I saw that someone say a lens will only be valid for 1 year. Then the snapcode will be deleted.
But I have several lens uploaded 1 year ago, and they can still be used and searched. Is it true that I need to update the lens every year by press update existing lens?
