After power cycle, in Timelapse modes, video settings are not retained and are always restored back to default 2,7k. Video attached.

Already reported this to DJI and they are aware of the issue and said they are working to resolve it in a future firmware.

I have the latest firmware: 01.01.08.70
@DAFLys - if issue is noticed by many people, the more likely it will be fixed...

Hello, there. We're sorry to hear about this situation. Please know that our team has noticed this situation, and working to have the situation optimized in the near future. Thank you for your understanding.

It remembers your selected setting if you use the "Custom" option in Timelapse rather than one of the pre-defined settings such as "Sunset".

That’s right. Make the change in Custom and it’ll be remembered
