Ive deployed multiple times to try and figure it out, and in short term - deployer of contract becomes the owner, but for some reason when i deploy the contract, past tx hash into bsc, copy contract addres and add the tokens criteria to my metamask wallet the balance shows '0' -
i can't figure it out.
Please find the thing i have missed!!!
