Hi Nik, I’ve sent you the log via email to support@gentlemencoders.com. I’ve tested copying photos from the external SSD to the iPad‘s internal storage via the files app and I don’t get the same problem, deleting them via Nitro works fine.
Another observation from today: sometimes when deleting just a few photos (about 5 or so), Nitro resumes after being unresponsive for a few minutes and I get the „couldn’t communicate with a helper application“ pop-up.
