Causes errors in your entire account. I am no longer able to log into my account from a computer since downloading this app. I was told it was because the system "doesn't like when it is open in the app and other places at the same time". This persists even when the app is force stopped on my phone. This has led to delays in my tax return due to certain documents viewable on my phone, not formatting correctly on my turbotax expert's pc (also took an entire week before even looking at my doc).
