Duo has a TrustPilot score of ~1 for a reason.I paid for the annual subscription to the DuoLingo Super tier, as well as the additional Family pack version. It's advertised as not having ads. But I still get constant ads to "upgrade" to DuoLingo Max. It's fraud advertising, and customer support is non-existent. I thought I got "Upgraded Support" when I paid for Super. I guess 0 support * anything is still 0 support. Garbage, unethical app.
