AWS SNS Delivery retry policy Total policy retry time cannot be greater than 3600 seconds

I am trying the AWS SNS Delivery retry policy to have it retry every 1 hour for 10 hours.

My setup is:

Minimum Delay: 3599 seconds, Maximum Delay: 3600 seconds

But I am having an error that it says:

Couldn't set topic delivery retry policy. Error code: InvalidParameter - Error message: An error occurred while setting the attribute delivery retry policy (http/s). Invalid parameter: DeliveryPolicy: http.defaultHealthyRetryPolicy: Total policy retry time cannot be greater than 3600 seconds

I have tried making the values around 1500-3599 and making sure that the Minimum delay is lesser than the Maximum delay.

It only works when the values are within 20-120 (or a few hundreds but definitely not 999)

Anyone here who has been successful setting it up at every hour retry? Thanks
