Hi Kevin, sorry that you experience this. Is it possible to open a ticket so that we can get a copy of the app + SP logs? This can help us to investigate.
Meanwhile, you could try to create an antipattern that Performance Bot should detect (see the list here, https://docs.mendix.com/refguide/performance-best-practices/). Then run the Performance Bot using the inspect button to see if Performance Bot works.
Thanks,
