I am still a Rookie regarding bitcoins and therefore apologize beforehand if I might use some words wrong.
I started a bitcoin wallet through a provider some years ago and bought some bitcoin. The wallets they provided were in the cloud and the didn't want to continue with that solution after some time so they discontinued their wallets. At that time I transferred my bitcoin to a new wallet. This week I transferred the bitcoins back from the new wallet to the old wallet as I still had the old address written down and I thought that I could sell the bitcoin through my old provider (had forgotten about that they discontinued their wallets). I can see the public key or address which contains the bitcoin. I have the 12 word recovery phrases for both wallets. I tried to recover my wallet with the 12 word phrase but the balance is 0. When I log on to the blockchain app i can see the old address under "imported addresses" but it says "not payable".
Is there any way to access these bitcoin on the old address or are they burnt?
I tried the steps in I have my 12 word seed from @Abdussamad, even with different import methods but unfortunately it can't see the balance.
Really appreciate your help. br
