Hey @itsmeayyub,
In your case you have to use created_time (or the last modified) to cover the condition for the days that have been passed.
Let's say that you want to track the 3 days since the record created in your base:
formula in Send_reminder_1
if(AND(
{Payment_made}=!True,
DATETIME_DIFF(TODAY(),created_time,"days")>=3
),✅,Blank())
formula in Send_reminder_2
if(AND(
{Payment_made}=!True,
DATETIME_DIFF(TODAY(),created_time,"days")>=6
),✅,Blank())
Please keep in mind that you replace the Blank response with an ❌ emoji or what works better for you.
Does it help?
Yours sincerely,
Dimitris Goudis
