Let’s first confirm whether any mobile visitors have seen Variant B in your A/B test report. You can check this by filtering your report by Device → Mobile, and see if there are any visitors to Variant B.

If there are no mobile visitors for Variant B, it might be related to the stricter security measures of mobile browsers, especially with Safari on Apple devices. Safari tends to block external tracking scripts more often.

Additionally, if you're loading the Mida script through Google Tag Manager (GTM), that could be the issue. GTM scripts are known to be blocked on mobile browsers in some cases, leading to variations not showing up as expected. To ensure smooth testing, we recommend loading the Mida script directly on the page rather than through GTM.
