Page Transition missing, Accidental X-Axis scroll mobile

Dear Webflowers,

I am trying to troubleshoot 2 problems which seem to be correct in the preview but are different on the published versions.

01 The page transition starts with an animation which lays over a mask. They loading is delayed through the code snippet found in the page transition tutorial section. After mask has moved over the page the page animation on load is supposed to move the mask back to the right out of frame. In the preview this part is shown. However this part is missing on the published site.

02 The mobile site seems to have the correct size in the mobile preview and on desktop browsers in dev tools (chrome). The problem is on a real phone i can scroll the site to the right which is not supposed to happen.

Has anyone encountered the same problems or some hints where I might be missing?
