There Are 2 Types Of Changes on your gig.
One Is Minor changes. Another one is Big changes.
You can make minor changes. Suppose you want to change the description, image, and tags. Don’t do this. It’s a significant change in your gigs.
You can follow this:
First-day change description
Second Day Change Image
The third day Change Tags.
Also, try to change it when you have a queue order. If rank falls, you can come in position again because of your order.
I hope it will help you.
