Hi everyone,
I've created several instant flows connected to Excel files.
In those Excel files, I have a formula that tests whether a date is equal to the current date.
In the following example, I use the now() Excel formula to test the date. As you can see, we have a birthday to celebrate ...

For your complete information, the hour associated with thoses dates is 12:00 AM 
This morning, my flow fired on due time:

Though the flow was declared "successful", no message was posted on Teams.
This happens randomly. Sometimes my flows work, sometimes they don't.
Does anyone have an explanation and better a solution ?
Thanks in advance for your kindly help
