Looks like automatical dataset updating is not always needed.
Use-case:
I use Finam HDP (Russia pac). A list of 400 stocks, Daily TF. When I run backtest for the first time the data loading process is slow – 3-5minutes. The system is trying to update data. The next time I run the same backtest this part will be very fast. Looks like OK.
But.
I guess when I restart the WL7 it will try to start the slow updating again, and sometimes restarting WL7 is something I have to do, for example when debugging a strategy using Edit and Continue feature sometimes VS2019 says that I must restart the application to apply changes.
I don’t need my Daily data to be updated more then once a day or a week/month.
Today is Saturday, no new data today, so if I updated data yesterday for example, today and tomorrow these 3-5 minutes are useless.
What I want to say – maybe you can make this updating before the backtest optional or delete this stage, so to separate this special process from the backtesting process.

It is optional, it won’t occur when Offline Mode is enabled from the File menu.
Thanks, I didn't know that.
I will definitely use this option. But again another piece of advice… you didn’t ask for)). This works like: you are doing something (turning on offline mode for example) and you have this unobvious side effect, that help you to solve the exact problem, but the whole complexity grows.
Will I be able to update data using Data Manager? If yes - why this mode is called Offline mode, if no - this instrument is not very convinient for the cases like this.

Think "Enable/disable on demand data update" when you read "Offline mode". Like in WL6.
Since updating data in the Data Manager is such a proactive thing, it makes sense, to me at least, that it should still work in Offline Mode.

Thanks, sounds reasonable.
