Hello.

I have created a wallet and imported one address. I don't remember back then, if I was able to add only the address (as watch-only) or if I imported the private key. But after this, is it possible to add more addresses I have, as wathc-only addresses, both in the desktop and mobile versions? I'm using Debiam Buster and Andorid phone.

I searched about how to import wtch-only addresses, but all I can find is how to create watch-only addresses. Not what I need. I already have a wallet created and I want to import more watch-only addresses.

Is this possible?

Yes you can import watch only address. I am not sure what exactly is confusing you
Go to New > Enter wallet name > Click Next > Select Import Bitcoin addresses or Private Keys > Copy and paste Bitcoin addresses you want to watch

You can also use master public key;
Go to New > Enter wallet name > Click Next > Select Standard wallet > Use a master key >  Copy and past your master public key > done

I think the OP is asking how to import more addresses to an existing watch-only wallet.

To OP:

In the desktop version, you can add more addresses to a watch-only wallet.
To do so, click on "Wallet" at top of the window and then select "Import addresses".

Note that if you have created the wallet using private key(s), you cannot import a watch-only address and you can only import private key(s).

You just have to remember these:

• If it's an "Imported" wallet, you can add more keys (for Imported) or addresses (for Imported watch-only) in the already-created wallet using the options explained above.
• If it' an HD wallet like "Standard", "2FA" or "Multisig", you can't add more keys/address aside from deriving your keys beyond the gap limit.

is there a reason why you are messing about with random private keys and addresses when you could create an HD wallet with unlimited addresses? a standard electrum wallet with seed is exactly that.
