Image Upload Feature in ChatGPT Not Working on Arc Sphere Browser

When accessing ChatGPT via the Arc Sphere browser, the image upload icon appears in the chat input area but does not function — clicking it produces no response or fails to trigger the file selection dialog. This issue does not occur on other browsers such as Chrome or Firefox, suggesting the problem is specific to Arc Sphere’s implementation. The likely cause is either file access permission restrictions within Arc Sphere’s environment or a compatibility bug between Arc Sphere and ChatGPT’s image upload API.
