Hi all

I have a thumbnail virtual column with this code:

CONCATENATE(“https://drive.google.com/thumbnail?id=”, [_ID])

where [_ID] is Google ID like this: 1xyojOgE5IdAvZeB4Qw4zZRJzLVKIhtA6

https://drive.google.com/thumbnail?id=1xyojOgE5IdAvZeB4Qw4zZRJzLVKIhtA6

The two prints bellow: Desktop (ok) and Mobile (not ok)

desktop.png

What if you try making the final URL?

CONCATENATE(
  "https://lh3.googleusercontent.com/d/",
  [_ID],
  "=s220?authuser=0"
)

Thanks @sk

It’s seems like better. I think there are something likes cache or deploy. There is a delay to show the thumbs, both on desktop or mobile. But your code is better. Where do we get reference like those that you gave me?
