I think what he's saying is that the only wallet he managed to sweep funds with from a taproot address, is Samourai wallet and according to the wallet's site, it should be possible to send funds to this type of address[1]. You can't generate them though.

But I think most wallet will do that because bitcoin users can send from one address type to another because one address type is compatible with other different ones because that is how it is. Although, I have not tested sending from pay-to-taproot address on one wallet to wallets that are not supporting it like Electrum, but I think such reputed wallet will make such transaction to be successful.
