I have a few questions about wallets

I set up a wallet on eidoo that I have a btc balance on. However if I use the recovery phrase to link it into coinbase wallet app the balance doesn’t show. Now I haven’t linked the coinbase wallet to my coinbase account so I’m a bit confused as to why my balance is on one but not the other. I sent over a small amount from my eidoo to the coinbase wallet that has gone from eidoo to coinbase as if it was a different wallet. Any ideas?
