Beginner problems. Can't buy - Invalid address


I am a beginner of that. I downloaded daedalus 3.0, create a new wallet.
Now if i want to buy cardanos with credit card, it says invalid address.
I tried to buy different places (coinmama,, etc), but always says ‘‘invalid address’’
So i tried yoroi wallet and same problem.
And all addresses begins addr1…
So what am i doing wrong or can someone help?


Created shelley wallet right?

Here are the exchanges which were migrated to Shelley (u slould use one of them… binance,,litebit,etc)

As u can see… [ Coinmama ]Shelley integration in progress

goodluck and don’t forget to delegate your ADAs for passive income!
