2-Factor with Authy?

Recently I found out about Authy and how it works, so I've decided to start using it in general (beginning today) so far things have gone well, until I attempted to link FAKKU! with authy. I make authy scan FAKKU!'s barcode, but Authy refuses to authenticate, I just get stuck on a screen that tells me to click "Done",after typing in a my username, which i do and than just infinite loading happens :0. This is on a iOS device.

From the app click the top right menu and select add account.
If it prompts for backup password stuff you can skip it by selecting the top right menu and clicking skip, or you can do it, your choice.
Scan the QR code.
It'll ask for a name, write FAKKU for it as it's actually for the service name.
Click done.
It should now redirect to a new page and show a code.
Input the code on fakku to confirm it.

I have tried this to, and just tried it again to make sure, but once again it just gets stuck on the "Done" button being pressed, with a circle spinning infinity.

That's strange. I just tried it and it was able to finish fully. is your app fully updated?

Yes, I only discovered the whole 2 factor with app a day ago, so I just downloaded it yesterday and checking App Store doesn’t indicate any update has happened. And I have successfully done this with other accounts on other websites I have since I started using authy yesterday, FAKKU! Was the only one to show this issue. I will try this again this evening and see :3

Yes this issue is til happening :C and it seems to only be with FAKKU!.
I've been able successfully use it for 8 other sites so far.

How you tried it in another authenticator app like google's authenticator?

Thankyou for solving my issue ! :3
