Add clustering in scope web version doesn't respond..?

[Erinke89]

Hi,
Thanks for the great tools you make!
I'm probably missing something really obvious, but when I try to add clustering (2 column csv file as described) to a loaded loom file in the Scope web app, I do get the pop-up warning me this is a permanent change, but when I click OK nothing seems to happen. The submit button very shortly changes in "processing" but then goes back to submit and I stay in the add clustering screen indefinitely. When I return to the homepage, no clustering was added.
I also tried adding the clustering to the loom file in R with add_seurat_clustering(), following the vignette instructions, but this also doesnt seem to translate into clustering being visible in the scope web app...

Can you please tell me what I'm doing wrong? Many thanks!!
