Re: Creating a bitcoin wallet on electrum and trying to recover it on wasabi wallet
The only flaw i can see in bip39 is you don't know the derivation path which can be really confusing. I once had some money stuck on an address and I couldn't find out what derivation path the stupid wallet was using. Even when I knew the seed phrase. if they could fix that then bip39 would be perfect. 
probably even better than the way electrum does it since bip39 is way more widely supported right?
Either you are using this type of wallet or you are not getting it right when you were importing the BIP39 seed phrase. BIP39 has a specific derivational part. probably even better than the way electrum does it since bip39 is way more widely supported right?keys and addresses derivation have derivational standard which are BIP44 for legacy keys and addresses, BIP49 for nested segwit and BIP84 for native segwit. So either you used non reputed noncustodial wallet for the seed phrase generation which keys and addresses derivational path is not following the BIPs standard as indicated above or you are getting it wrong.
To be careful of the private key wallet we are using these days
If you used a wallet that follow the BIP39 standard and also BIP44, BIP49 and BIP84 standard, then you should be able to import the seed phrase successfully on reputed wallets that follow the BIP standards. Also you can check BIP39 on Electrum and the importation will be successful, choose the right derivational path and your coin will appear. You can also use Bluewallet.
