Smartsheet Picture not Showing

[strisnojoyo]

I have been using this guide.

It worked before. But it suddenly does not work anymore. The picture won’t show up. It started like two days ago. Please advice.

Edit: Is there an issue between the integration of Appsheet with Smartsheet?
I also try take a picture directly from Appsheet app, it usually pop up on Smartsheet after I sync. It pop up the picture on Smartsheet just fine, but after sync, the picture on the Appsheet itself, is not available anymore, it shows the same triangle exclamation mark on the picture. Please advice.
