Severe Problems!
Like many others, this app has severely put a hold on my business. I recently transferred to a new iPhone, restored my new phone from my backup, and Google Authenticator completely erased all of my accounts that were linked to it.
Instead of offering a feature that would allow me to transfer all of my accounts over to my new phone, I now have to contact each site one by one to reset my 2FA. Totally unnecessary and overlooked by Google. Not happy!!!!!!!!
