Can anyone help me with activating my tez address. I entered my contribution address on the keychain site and it said that the address is invalid. I checked the address on the contribution page and it gave me the amount of Tezos allocated to that address: which means the address is good. Can anybody help me with my problem. How can I have a valid address when I check contribution, but not valid when I try to do kyc?Your help and comments are appreciated.
