When we use OCR, the image is not worth saving. We need it only for extracting text.
OCR need high resolution images, so when adding a new row with an image and OCR, it takes time to sync, because of the image.
You can avoid this by simply adding an Action to your Form:
The Action is: Set the image column to nothing.
With this, the image will not be uploaded to your cloud storage and will not be added to your sheet.
