When someone fills out my form and clicks submit they get a success message saying "Your content has been submitted", but it can take 5-15 seconds before this pops up. I have added loading effects while the data is uploading, but I would like to make it even clearer that their data is being uploaded, so there is no room for confusion at any point.
I have found guides on adding lightboxes and other events when a form has been submitted, but I can't seem to find any guides during the upload of the data. Ideally, I would like it to be a big box in the middle of the screen with a loading icon that disappears when the upload is finished. If you have any suggestions to a workaround or different way to achieve this, I would love to hear it!
I highly appreciate any help.
