Re: "Invalid token" error when accessing legacy blockchain.info (now .com) wallets

Seriously, it's hard understand the full situation with that wall of texts while talking about separate blockchain(dot)info wallets 
It would be better if you identify which one was in that previous attempt and which one was recovered in that last part. (e.g.: walletA, walletB)
I tried https://login.blockchain.com/beta/legacy-pages/forgot-password.html?guid=????????-????-????-????-????????????
but it throws Unknown word rejecting
Unknown word midas or tickers
Unknown word incessant
...
...
and so on.
You're not the only one who got that error when pasting their version3 mnemonic to their legacy import (forget-password) page.but it throws Unknown word rejecting
Unknown word midas or tickers
Unknown word incessant
...
...
and so on.
However, even if it proceeds, it'll just show you your password which you already have.
Or is this for another wallet aside from the one your tried to login and the one you've successfully imported to Bitcoin Core?
Now I wish there are ways to make https://login.blockchain.com/beta/legacy-pages/forgot-password.html?guid=????????-????-????-????-???????????? available again,
or make download-blockchain-wallet.py work again (which it throws errors)
For the former, you may ask them to support v3 mnemonic (e.g. via Bug Report Issue),or make download-blockchain-wallet.py work again (which it throws errors)
Here's GitHub Organization: https://github.com/blockchain, try it in their "blockchain-wallet-v4-frontend" repository since their current v5.0.87 beta wallet isn't available.
For the latter, compatibility was broken.
The owner or the new BTCRecover fork has a tutorial on how to download the wallet file here: /docs/Images/download_blockchain_com_wallet.png
However, it's the same result from: https://blockchain.info/wallet/<YOUR_WALLET_ID>?format=json which doesn't work in the latest version.
