I am also having issues with Tumblr import. Has been over 48 hours. I see many others are having issues and I read the email stating there is a massive amount due to the new Tumblr restrictions. I’m just going to let it run but I know it said to contact support if it was over 24 hours.
I’ve double checked to confirm your import is still queued. It didn’t cancel. But please do reconnect to your Tumblr account if you’ve disconnected it, as that could be preventing it from starting.
We’re processing quite a few imports from Tumblr at the moment, which is causing a backlog of imports in our system. While it may look like your import failed, it’s just in line for processing, and luckily it’s still in the queue. At this point I’m not able to give an estimate on how long it might take to catch up with the backlog, though.
