Images not displayed in tiled gallery.

Hi guys, I just updated the Jetpack and I discovered this really bad issue: some images are not displayed in the tiled gallery. Check this out as an example: https://giacomomantovani.com/works/

I’ve read others threads about this same issue, but I couldn’t find a working solution. So here I am.

In order to understand what causes this problem, I have tested the following:

1. Disabled the CSS code I have created to personalize the website. This didn’t solved the issue, so I put it back.
2. Disabled all the plug-ins one by one. The result is that the Jetpack is the one responsible for this issue.
3. I have tried deactivating all the Jetpack plug-ins, the images are displayed. I have then turned on again all the plugins including “tiled galleries” and again, the some images don’t appear at all.

Anyone knows hot to solve this issue please? If not, is there a way I can download and re-install the previous version of Jetpack (which was working fine)?

Thanks a lot.

All the best
