How to Turn off automated handling time? The system Will not turn off the automated handling time

I haven't seen this question answered in any of the threads regarding automated handling time.

We have automated handling time turned off because we ship everything (before cutoff) the same day . In 9 years we have always operated that way. Amazon wants to set our handling time at 1 day, because their metrics show all our items somewhere between .25 and .75 days handling. We have it manually set to zero days. In addition, we have "same day" turned on for each and every one of our shipping templates.

I have always assumed that the "same day" toggle on the shipping templates overrides the general handling time anyway- whether manually set or automated- but just in case I have left the automated handling turned off.

Now the new OTDR metric instructions/explanations seems to be saying that to have a late delivery exempted from the metric you must use ALL 3 of the following:

Ship using SSA, ship using Amazon buy Shipping, and have automated handling time turned on.

So my question is, if I turn on automated handling time to give myself the OTDR protections , will the "same day" toggle override the one day handling that Amazon wants to set ? If not, I would lose orders because Amazon would show customers extended delivery times.

Before someone asks, we ship 5000-6000 orders a month and our current OTDR is 95.14%

Mods- can you help ?,

Well not sure if anyone else is having an issue with this automated handling time vrs sku set times. We mailed out over 176 items in previous 14 days and 159 were delivered on time.

The issue is when checking the shipments listed under On-Time Delivery Rate we have fallen to 90.34%.

But when you go through the orders all shipped on time and were scanned by carrier on or prior to promised shipping time or even had two orders picked up two days early (we have a sku handling time of 3 days for our handmade products)

But as they were late being delivered by carrier I am at fault as I turned off Automated handling time and set back to sku handling time as it was having us ship in a day which we could not maintain. Been selling for a few years and always ship by promised date and if carrier has issue not my fault. No longer is this the case

I know have been informed, because I turned out Automated handling time even though orders were scanned in by carrier on or before promised ship date it will from now forward hurt your on-time delivery metrics unless you have the Automated handling time enabled if the package is late due to carrier.
