Hi,
Print screen below is the standard reminder flow I'm using.

I set 2 days to remind. I have tested it and working fine. After tested, I decided to use it and turn it on. The flow is suppose to send reminder on 8th August 2019. But a reminder email was sent right after I turned on the flow on 7th August 2019. Next day, another email reminder was sent on 8th August 2019 and this is correct. Did anyone experienced the same? Flow is triggered and executed when turn on and didn't follow the conditions have been set?
I noticed few are posted issue on Flow only trigger when they turn off and turn on it, which should works automatically. I'm interested to know the common problems on this to avoid any flow is fail to trigger automatically.
Thanks in advance.
