Another very minor issue:
One of my accounts requires multi-factor authentication via a PIN which is sent by text message. On Mac, the browser will recognize that a PIN has been sent and then auto-populate the input dialog with that PIN (it will also delete the text message which is super handy).
For whatever reason, it doesn't work on Simplifi. I believe the modal which pops up where you enter the PIN isn't recognized. Once I manually enter the PIN, it then auto-fills in the "search transactions" window. :)
Not sure if this is an issue with Simplifi or Apple, but would be great if it worked as expected. In case it helps, it works on mobile perfectly. Thanks!
