Missing thumbnails

Web

Firefox prevents the app from generating thumbnails if the "block canvas fingerprinting" setting in Firefox is enabled (i.e. privacy.resistFingerprinting is set to true in about:config). The app needs the canvas to generate thumbnails, and that Firefox feature blocks access to the canvas. Ideally, Firefox should be prompting for a permission, but some users have reported that sometime it silently blocks access, and turning off that setting works.

Similar issues may arise if you are using an extension that blocks access to the canvas.

There is currently no functionality to regenerate thumbnails in the above cases. You will need to upload the affected files again.

Ente skips over files that have already been uploaded, so you can drag and drop the original folder or zip again after removing the files without thumbnails, and it'll only upload the files that are necessary.
