Don’t know if this is the right place to report, but there seems to be a grammatical error in the documentation: https://docs.sentry.io/learn/rollups/ under Group Stackings. You say…
This means that if the stacktrace is modified from one event to another exclusively in PARTS of the stack that IS not related to the application, it still groups the same.
…caps provided by me for emphasis. I think you have a number agreement issue. If “is” refers to “parts”, it should be “parts of the stack that are not related…” This is non-trivial, IMO, because you might mean that it’s the stack that’s not related to the application or that it’s the parts that are.
Just thought I’d let you know.
