My lastest diagram version was lost

[Sorawid Juntachat]

Hi 

I created diagram on draw.io online and linked it with my google drive on April 16, 2024. Then I finish draw final version diagram on about April 23, 2024. But that final version diagram have lost when I try to login to change it on today. 

I tried to recovery it with Revision History feature but it show only not lastest version.

By the way, I export my diagram one ( but not the final version) at 9:16PM on April 18, 2024 and in the revision history didn't show this version too.

I notice that all my account has signed out from draw.io itself and the diagram have gone  since revision history "18/04/2024 18:36:11" . After this revision all version look the same.

Could you please help this?

Thanks,

Sorawid
