There are any limitations to change Gigs or modification gigs everything. this is good or bad if i change my gigs regular.
You have the right to change your gigs all the time you need. If you change your gigs every time, like change cost of your work or reduce advantages for a category of work , i think that is not professional but now, if you change your gigs to ameliorate your pictures, video or add resent delivery order that is good for me.
You can edit your gig any time you want, but I think it’s better to not edit more than 3 time a month, because on every edit the gig will be out of the search results for many hours.
your gig rank will go down if you do too much modification
