I have the same problems about the slowness of the site, starting with the log in, the following always appears on the screen
"Unable to login, please try again later"
After several attempts I manage to enter the site, but here comes the other problem which consists of the excessive delay in opening either a photo to see its content or uploading a photo, it is really extremely slow, I hope this situation can be resolved as soon as possible.
Regards
Tomi.
