Immersion upload not responsive
I tried to upload two short books (the Html page is less than 250k). When I entered the URL and pressed upload, the O started spinning but then after sometime it stopped and the upload process remained stuck (for both books).
I did not retry the same books because I was worried that it has been uploaded in the background...

even the plain text format has the problem (with only 50k content)
