So far I have never problem using Authy, so when I compared it with Google, Using Authy is simpler when we change cellphones, we can log in again using the same cellphone number and receive a code via SMS. I have experience lost the google 2fa code and can't login on 2fa. because of that, I prefer using authy for beginners who have weaknesses in storing data or code on paper.
From the very beginning I traded using Authy security. I think it's still safe and I feel comfortable with the automatic recovery feature and it can be used on multiple devices. I hope there are no other losses for me and other users later.
Then regarding the update problem, I checked in my application Authy that I have the latest version. I checked from the Play Store. Is this a little different from the one on the play store? Hopefully not. I see the details My update version is already in 25.11.
