Any way to have force regular clients to use mobile player until this is fixed?

Hi, still having problems with this issue.
Updated my site with new version (2.3.2 pro) yesterday. Have tried different machines and browsers, all with cache clearing etc. Still no luck.

Site: (10+ galleries in the menues there) e.g

Thumbnails are loading, but not the main picture. Works as it should from mobile devices.
