Hi if I do changes in the spreadsheet of a embedded google sheet/doc the refresh of the thumbnail is not working right. It works for the first refresh but when I am doing additional changes I have to wait a long time until the refresh button works again. In summary if you use the refresh button repeatedly in a short time it does not update the thumbnail or not correctly. You have to wait some time until you can use the refresh button (up to ten minutes or longer) so that the changes actually show on the thumbnail. This is kinda annoying and I'm wondering if there is a way to do this better. Additionally if I am turning to a second page (which need so long to generate at first) then the changes will appear correctly. But it is disappointing that I can not just use the refresh button to show the changes in the thumbnail and it is disappointing that the second page (or further pages) take so long to load the first time and every time after a refresh. Is the connection to the sheet/doc just not good/strong enough? I just used an embedded link is there another better way?
