Sorry - Resolved!
Just one small question: where and how I have to set the right Date/Time format to have the correct time in the calendar?
I mean instead of 12:00 to have something like XX.XX PM
My GSeet settings:
Locale: United States
Time Zone GMT+04:00
Display language: English
In my GSheet Date/Time displayed as 5/20/2020 15:00:00 and in Glide editor as 20 May 2020, 15:00
I was playing with different settings in Gsheet and in Glide editor but did not get needed result
