Conditional Formatting not Working on Sheets

Conditional Formatting not Working on Sheets

Hello,

I had some Conditional formatting rules set that have been working for the past 2 weeks. The rule is very simple that if a field contains a Date that is Today, the field fill color of the cell changes to Red and the text becomes Bold and underlined.
Now this has suddenly stopped working since the start of this week.
Can you please check the issue?

Best Regards,
Ahmed Fouda
