Depending on the type of data and your internet speed, uploading can take longer than expected. Here's a couple of reasons why this may occur:
The number one culprit is usually the WiFi connection.
PDF data takes the longest to upload. This is because more often than not, there are multiple pages in each file and we extract text for each.
Something somewhere has gone wrong. Try doing a hard refresh (command + shift + R).
If the problem persists, please send us a message in our in-app chat and we'll happily take a look at the issue together.
Hint: once it's in the "processing" step, you can safely leave the page as the upload is finished – especially for CSV data, the processing takes longer than the upload itself. This is because you are uploading only one file but that file can have many rows that have to be processed
