How to restore my Copay / BitPay Wallet?
I tried recover: https://bitpay.github.io/copay-recovery/ [...] No success.

I don't know why you put your recovery phase into a website. That seems a very risky thing to have done. The distinction between github.com and github.io is also something I'd find a concern that would make me hesitate.
A message like There are no record of your wallet on our servers. makes it sound like recovery of a custodial wallet but wasn't the Copay wallet non-custodial?
I would worry that having typed my recovery phrase into a website, someone will have already stolen any money.

What I would have done is download the Bitpay wallet app from the Google play store (after checking very carefully that the app authors are listed as Bitpay) and use that software's wallet &quot;recovery&quot; features. I would not use &quot;import&quot;.
If the balance showed zero, I would check for recent transactions moving the money away.
