It’s been painfully slow for me too, so much so that I had all but given up.
It even kept freezing when trying to add a new category.
I changed back to the old system a while back because the new system was so slow but I don’t think we have a choice anymore because they have dumped the old system all together.
Today though my internet reset and I had some success uploading which makes me think it’s all about the internet connection, if you have a slow system you will have trouble.
I even have trouble logging in here some days
Still, I might have to look for a new photo host.
