I am using Chrome on IOS.
After doing additional testing, it appears that this is only an issue on IOS running Chrome. This is not an issue when using Safari or Edge browsers on the same IOS device. I tried this on multiple IOS devices with the same result.
Also reviewed this doc: https://woobewoo.com/documentation/shows-all-products-on-category-page/. All settings are correct. Again, this is only impacting mobile users. Desktop view is fine.
Also confirmed that the “Display Only Children Of Current Category” option is enabled under Content Options.
