Hello @Viktor,
Could you please conduct a test using different devices? We have tested your website on several devices and browsers from our end and did not encounter the issue you mentioned. This suggests that the problem might be related to a specific configuration on your browser or device, possibly even for a specific website. We have attached a video above demonstrating our tests on responsiveness from both our demo and your website, showing identical sizes and aspect ratios on both. Additionally, we have attached a video of our testing on an actual mobile device (not just a desktop browser in responsive mode), and it is also displayed correctly. If you continue to experience this issue, could you please provide a list of the devices you have tested?
