> Metered connections are network connections that charge by volume of data transferred. That happens, for

> When one tethers a 4G mobile phone to a laptop, it is possible to select that the connection is metered, to

> I was unaware that OneDrive deactivates itself in metered connections even if I ask to synchronize data.
> When I opened a big file (the ones that OneDrive typically removes from the computer to save space and

Thanks, I've now added an entry in PROBLEMS about this, and I'm
closing the bug.
