A lot of crashes shown in App Store Connect but no crash reports from multiple sources

Hi, App Store Connect analytics showed there are a lot of crashes happening recently, about 500+ past two weeks and average 40 crashes daily. However, Xcode is only showing very few crash reports (5 different crashes occurring in total 16 times). What's more, our two other crash report sources: Firebase crashlytics and instabug also reported only a few crashes that seemingly align with Xcode (4 different crashes occurring in total 10+ times) in the time range, far from the number of ASC (500+).

Since we are unable to achieve most of the reports expected in ASC Analytics, we are unable to debug and resolve all these potential crashes.

Any ideas on what's going on? Can ASC sometimes provide false signals or is there a way to find these hidden crashes' reports?

Anyway, whatever the numbers, it is apparent there are bugs to correct here. That should be your top priority: intensive testing, on a variety of devices.
