Very sorry if this has been answered but I have checked and tried the responses in the few posts I have found but still no success.
I have a built a few views taken from slices that I use for menus. I use a card display and list and have a field in my table for icons.
I can upload icons fine and everything thing looks great but often on refreshes or sync many icons change to the grey triangle.
I have cleared cache, turned off Secure Image access as recommended but still the same issue.
My app connects to tables in my Db stored in Google Cloud Console and the data type in AppSheet for the icon field is set to Thumbnail (I had it on image previously)
Any guidance would be great and thanks
