In episode 25, when we choose the meeting room, we choose the room at the beginning and then check whether it is empty at this time and date or not. I do not want to take this step. I want it to calculate the rooms that are able to receive the meeting, exclude the busy rooms and choose one of the rooms to receive the meeting. Is this possible or not

Thanks for your videos, but I am facing an issue - let's assume we have user A and B .
If User A is access in the app on 10:00:15 but not key any data, even NOT SAVE yet the app, just keep opening(So not entry yet in the source G-sheet ).
On that time User B is access in the appsheet for eg. 10:15:00 and booked BOARD ROOM for 11:00:00 to 12:00:00 and Save, entry also in the data source.
After a moment, USER A is continue entry the data BOOKED ROOM FOR "BOARD ROOM" for the same time 11:00:00 to 12:00:00, he could save the app without pop up any rejection or warning.

The issue is, if someone is entry earlier than another use, without saving or close the app, this formula is not working for it. I have try to set NOW() in [Entry Time] but the time is not continueting just shown as the entry time. I have search FORCE SYNC every one minute for every single entry time, but not fournd the solution . Sorry for long test .

Could you please help for my problem or guide me or advise me please . Thanks a million.!
