I see that you can't enter a mycelium 12 word seed in electrum or an electrum 12 word seed in mycelium.
Presumably they both use bip39. Why are they different?

Electrum uses a non-standard seed phrase checksum calculation method that is NOT BIP39 compatible... even though they use the same word list.

For these reasons, Electrum does not generate BIP39 seeds. Starting with version 2.0, Electrum uses the following Seed Version System, which addresses these issues.

At present, on desktop Electrum you can import Mycelium (and other) BIP39 seed phrases (simply click the "Options" button on Seed entry and select "BIP39 Seed", leave Derivation Path as default m/44'/0'/0' for Mycelium, other wallets may differ)... and because Electrum has a custom setup, Electrum phrases are NOT able to be used in Mycelium wallet.

Also, the Android version of Electrum does not currently support importing BIP39 phrases.

It should be work since they are the same format.. maybe you misleading or forgot some words better to check them carefully
Check this for list of words https://github.com/bitcoin/bips/blob/master/bip-0039/english.txt
And maybe you put a wrong spelling ..

Are you using desktop electrum?
I'm using the android apps of both wallets.
Spelling isn't a problem, electrum uses autofill.
I don't think I made any mistakes. I can try it again, but it would help to hear from more than just one person what their experience is.

Limited in number. Limitless in potential.

Are you sure? they have the same format, And I tried it too many times from mycelium wallet to electrum wallet and vice versa but it works.
Make sure that you pasted/entered correct seed/words in order with correct spelling. Because even one word is misspelled or you pasted the seed in not order, then it will show a new set of address and different from the other.
