When Mobile Accessibility is enabled, we do an additional scan of the website to simulate how it renders on a mobile device. This data is used to pick up device-specific code that only loads when a website opens on a mobile device. Based on this mobile rendition of the website, we can perform two additional checks in addition to the accessibility checks that already run on the website.
Essentially, these two checks determine if a web page is properly responsive. Responsiveness is a basic requirement for having an accessible website. The checks are displayed in the user interface and can be filtered out of the other checks. They are also displayed in the Web Browser Extension.
Check 1: Is pinch-to-zoom disabled?
Some websites have, on purpose, disabled the option for visitors to be able to zoom in on a web page by pinching with their fingers. This is not an accessible experience, as visually impaired users should always have a zoom option, even on a mobile device. This check generates a flag if pinch-to-zoom is disabled.
Check 2: Does the web page require two-dimensional scrolling?
If a website is not properly responsive, there might be scenarios where a user needs to scroll both vertically and horizontally to read a paragraph of text or view an image. Typically, this happens if a website owner has not defined the image size for mobile devices, and the image displays in the same size as it would on a desktop computer (meaning a visitor needs to scroll up and down and sideways to view all of the content). This is not an accessible experience for visually impaired users and users with motor disabilities (it is very strenuous for your wrist/arm to scroll in two dimensions). This check generates a flag if a web page requires two-dimensional scrolling.

When the mobile scann is disabled, it applies to all domains in the user plan. This feature is closely tied to accessibility scans and the feature must be turned off from the support team end. No accessibility scans are done until the accessibility feature is turned on again and reconfigured. You can set this up. See the links below for instructions.
Turn on and configure accessibility scans for each domain on the account.
