2TB microSD card support

Hi,

the Insta360 X4 support page states:

Do not use [...] memory cards larger than 1TB.

However I would love to use the 2TB cards from SanDisk. Either

• the SanDisk Extreme A2 2TB
• or the SanDisk Extreme Pro A2 2TB.

Has anybody tried either of those yet and can report if they are unofficially supported?

Or maybe Insta360 can share a technical reason why cards exceeding 1TB of space are not supported?

Thanks in advance!
