Hi @sr3, @uliana.bruno & @eoinparkinson. If your issue is the same as the one we identified for @jonathanvalgarlh4ow, we should be able to fix it for you. We just need to remove the corrupted data sources from your account. Do we have permission to do so?
We also have a fix for this which should be coming out shortly. It will notifiy you that your data source(s) are corrupt and allow you to delete them yourself. Sorry for the inconvenience!
