Thanks to feedback from a few customers, we've made a couple small tweaks to the workflow when you upload a CSV to create new readers in bulk.
Once you trigger the import, we'll now kick you to a separate screen, where a progress bar is displayed.
Once the import is complete, you'll see a confirmation message:
You'll need to click the Return to readers page link to head back to your Readers page, which includes your newly-imported readers.
We hope this makes it a bit clearer when the reader import is complete.
