Hello, Suji
You mentioned that have adjusted the Reminders in the Settings option. After activating the Reminders and days for the first notification and the regular ones, make sure you SAVED that.
The setting will be applied only for NEW envelopes sent. Those sent before you adjusting the settings will not inherit that.
To isolate if the issue is happening in the eSignature side or Power Automate, send a new Envelope from the DocuSign eSignature Home page, in the Advanced Options of the envelope verify if the reminders are set on it, if so, send the envelope after adding recipient(s) and Sign here field or others. If you set the first reminder as 1 so in the next day you will get the Reminder Notification, I mean, your recipient (signer). One day is the minimum interval for sending reminders.
If doing this, you see the reminder was sent so it’s something to verify in the Power Automate side, Perhaps in Power Automate when you are setting the step in your workflow there is an option to active reminders.
I hope that helps!
Best,
Alexandre
