Thank you for the reply!
How about a way to "watch" my wallet, using the master key? Is this possible using something like MyCellium and would it pull through all the seed addresses generated by the master?
I must honestly say i have never done this myself.
A couple things: make sure you use the correct master key (the master public key, starting with xpub, found in electrum via wallet -> master public keys).
Once you have this master public key, you can try any android app and see if it works, the master public key can only generate the public keys, so there's almost no risk involved (since no private keys can be derived from this master public key).
The master public key is able to generate all addresses that are generated in electrum when using your wallet.
