Yes, I've tried Electrum. It does the same thing. Creates a wallet with no funds using the 12 words. I created another wallet on Electrum using my lost wallet address ID and it created a "Watching Only" wallet that does show the funds.
Try to do this:1. In Electrum: File -> New/Restore -> Standard Wallet -> I already have a seed.
2. Write your 12 words from Copay.
3. Click "Options" -> Check 'BIP39 seed" -> Next.
4. Leave the field like that (m/44'/0'/0') and click next.
This wallet should be the same as the one you originally created in Copay. If it's not, then something is wrong (maybe the 12 words seed?).
That's exactly how I set up Electrum. It just creates a empty wallet with no bitcoins on it. I can't see how the 12 word seed is wrong. When setting up copay for the first time on my Android phone, I typed the words in note pad immediately. The next step in the set up process asks me to select the 12 words in the order it was giving. I selected the 12 words in order by what was I typed in notepad, and completed the setup. I checked each word for spelling by comparing them to the word list. Each is spelled correctly and one space between them.
