Re: Get file content won't get updated Content
Hi @Anonymous,
According to your description, I created a similar flow with you to test this issue. I got the same issue you mentioned. Though the row had been added to the table, action Get file content couldn’t get the updated contents.
Then I tried to add an action Delay before the action Get file content. When trigger the flow from PowerApps button, it was able to send an email with the updated info.
I assume that the Get file content action runs directly once the Add a row into a table completed. So it is not able to get the updated info from the table.
Please take the following screenshot for a reference and try again with it.

Best regards,
