The latest update to this App for Android (v.3.35) quotes a few improvements. Unfortunately BlackVue seem to have misunderstood the term "improve".

They say they've improved the password saving function but now, whereas the previous version used to automatically insert log-in details (so what's to improve), it's necessary to manually enter the password at every login, as the password is never saved!

I got round that failure by reverting to v.3.34 of the app, which does work.

Blackvue only respond with "we can only relay the information to the appropriate team and hopefully they will have this considered."

Hopefully.... !!!!
