I don’t think boh boh has the temperament nor intellectual dexterity necessary to be playing in this environment yet. Thankfully, you have more patience with pushy morons. Good luck!
Again, that is a problem of the wallet apps that you chose, not of Cardano.
Cardano has specified how seed phrases are to be handled and how keys are to be derived from them very early on in https://cips.cardano.org/cip/CIP-0003 and CIP-1852 | HD (Hierarchy for Deterministic) Wallets for Cardano. All Cardano wallet apps found at Showcase | Cardano Developer Portal do it that way and are mostly compatible with each other.
It’s permissionless. Nobody in Cardano can forbid those multi-chain wallets to do any strange thing they decide to do. But why on earth should we have any obligation to be able to deal with their shit? And they do not even publish what it is that they do there, so it is not even possible to implement it even if there would be a Cardano wallet app willing to do it for three users. Go and annoy them!
This is a problem of the wallet you choose. Those wallet has different format to Cardano keys because they are not the supported wallet for Cardano.
It must be frustrating not to be able to extract funds from your own wallet but if you experience problems with these wallet of yours then simply transfer your other tokens to a more legit wallet if you can then stop using them.
Really you should raise the issue to your wallet provider. The legitimate Cardano wallets have help desk from IOG, Discord, Telegram and from my personal experience these help desks respond quickly and efficiently. Blame doesn’t rest on the Cardano community on your problem.
my wallets…let’s specify…WALLETS not wallet, WALLETS
I think they are not making a war to Cardano or cardano’s users; even if they have probably distracted and/or poor developers, they manage multi coins and multi tokens and they have 2 different cardano private keys, so they are also managing cardano in two different ways.
These 2 multi wallets, in which all the other coins normally work or if they have some disruption in some days are fixed, with cardano they are completely stuck and they can’t do anything. One of them sometime work, after stop to work, after again restart to work, etc.The other one always stuck in sending. And both are able to regularly receive cardano. Ok it’s not cardano fault, it’s their fault with key format, maybe not updated, maybe poor developing. Maybe for next christmas they will be able to fix it. Is it better now?
