Customer Reviews

Very buggy, hope it gets fixed soon.

Just the tool I wanted, but frequently times out. It keeps asking me for access to my keychain when I’m not even comfortable about giving it the password to my accounts in the first place, never mind access to various financial account information. After a few times denying that, it goes to my google sign in page, where I have to copy and paste a number to get it to work. This lasts a minute or two, doing a few very slow transfers, and then times out again and I have to go through the whole process again. Google remembers what apps are connected to my account on other apps, why do I have to repeatedly log in on this one? I hope these issues are resolved soon, but I saw the same complaints about previous versions.
