Description

Google, Microsoft, Duo can successfully scan TOTP QrCodes and work flawlessly with this library. However Authy does not seem to recognize the token format at all, when it clearly states that this type of QR Code should be supported? Can you verify this ?

Research direction

No file or test is named. Start by reproducing the generated TOTP URI with Authy and compare it with the same URI in Google, Microsoft, and Duo Authenticator; inspect the library's URI-generation entry point. Done means identifying whether the URI format is incompatible with Authy and documenting or fixing the behavior with a regression test.
