Be carefull!

After restoring my account from Authy backup (after clean install of iOS), one of pin-generators was lost.
Re-enabling of account did not work correctly (Authy adds account after QR-code recognition without givin confirmation code for finalizing installation on external site.
Re-installation of Authy gives nothing.
Ms account, multi-device installation.
Very sad because this app is really cool and user-friendly
