Google Photos sourced galleries not showing up

Hi, I installed your plugin yesterday, and I had to authenticate with Google using the workaround you had documented. Because it was the only method worked for me.

I used the albums in my Photos account to create galleries using Photonic. It worked fine and I could see the galleries in private browser windows as well.

But when I checked them today, the images in gallery were not appearing. When I copied the source URL in one of those images, and opened it in a separate tab, Google did throw a “Forbidden” error screen. Out of panic, I had to quickly revert back to my old solution, as weekends have the hottest hours for my users.

I checked other support questions relevant to my issue, and I have no such JS errors in browser console either. Do you have a clue why this might be happening? An issue with my authentication process? I wish I could link you to a page this issue is replicated but I had to remove all the galleries from the live site.

Thank you very much for your time
