It was great working across all devices. Still works on my desktop but no longer works on Firefox for Android v57. It just won't login. I have to use the app and copy and paste for months now. So annoying I won't be renewing my premium subscription as this product is so useless to me I might as well use a password protected spreadsheet containing a list of my usernames and passwords. The app is rubbish as well and rarely pops up to log into other apps anymore forcing copy and paste again.
