Cant update presale date on website after launch
I am unable to update presale or public date after launch. I did public launch with no mints made and cannot adjust launch to a later date.
minter-dapp v0.02
More context is needed. What error message are you receiving?

I am currently still on Rinkeby for testing. I already set (test) launch date and I can currently mint.
Now I am trying to change launch date to a later date by adjusting the config file.
I then run npm run update_public_mint_start_date and the correct date shows up and I click y to confirm
I get no errors and I repeat the same for presale_mint_start_date with no errors however on front end I can still mint even after the update.
I remind you I am still on rinkeby for testing/learning.
Kindly let me know if it is an impossibility with rinkeby or maybe I'm badly interpreting something.
