I’m not sure if this has/is being addressed with Canvas specifically but whenever I am scrolling through Canvas liking things to download later, I get to the point where Canvas will give me this error…
I am not liking every single thing and sometimes there is 30 sec to a min in-between liking a creation.
If this hasn’t been addressed, please look into this as this can be extremely frustrating for players who like to browse and download items/creations from Canvas.
(If there is a similar link let me know so I can merge)
I believe this is a measure the devs have taken to prevent bot usage. Unfortunately, wherever there is ranking and a like system, there is bound to be bots, and although it can be bothersome when you are a real person just enjoying yourself at Canvas, it’s for the best.
I had a feeling that might have been the case in some sort of cooldown.
Oh yes, I’ve experienced this issue quite a few times myself. It’s truly unnerving =(
I thought this would happen if you flag more than 15 items for download or something ?
Only happened once to me I think.
It also happens with likes, at least that was the case for me a few months ago.
So it seems to happen when liking creations and also downloading but with downloading atleast you can continue downloading the creation it just gives you the annoying popup to click out of every single time
