Now, I have checked your site the CDN is activated on the site check here: https://postimg.cc/NLMkKBQM First please contact your service provider to disable the CDN and flush the server cache completely also, please disable the cache system from the server until your site is in the development mode you can enable the CDN and cache system again once your site will be live.
Try to check the site on any other Mobile on a fresh new browser and I am sure you will not face this issue anymore.
