In the parent task you granted us the new project "devtools" (Thanks!).
I just tried to create a new instance in it. I can go through the usual forms and select the image and name etc.. and submit it.
But after that nothing seems to happen. I don't see any new instance(s) in the list and the summary of the project keeps saying there are 0 instances.
I tried to repeat it 3 times also with a different size and name and i do not get any errors.
Could you take a look why instance creation appears to fail?
