I use your module v1.3.0 on my site Magento 2.3.4 and found wrong result when filtering in the backend for different interface locale.
For example, I have the two format date in Polish is DD-MM-YY and in English format is MM-DD-YY.
When I try to filter orders from 01 Oct 2020 to 31 Oct 2020 - system shows me orders result on December. Probably dates range as 10/01/2020-10/31/2020 is not correct and 10/01/2020 is not 01 October but 10 Febuarary 2020.
Do you have any fix?
