It took about 7mins to upload a 24bit 11mb file, which is much slower than usual and it's still busy creating the previews, so I'd agree that it seems to be slower at the moment. LANDR was also introduced to Studio One 3 I think, so perhaps it's purely a traffic thing?
Beep, I installed an early version of the LANDR desktop app and chose not to reinstall via the Newburyport update, so there's a good chance that my version number would differ to the one included in the installer.
