Thanks for reporting this, @meichen8050753. I noticed that you've uploaded a dSYM file. Could you provide your complete steps in doing this? The symbols are supposedly uploaded automatically by the Firebase Unity Editor plugin.

Thanks for clarifying, @meichen8050753. While we're trying to replicate the issue, I would like to ask for more context about this. When you mentioned that a third-party library does fine, could you provide its differences between the stack traces returned by the Firebase SDK and those of the third-party library? Could you also share the expected stack trace output by the Firebase SDK?

Also, have you encountered a missing dSYMs banner in your console?

Thanks for replay, @paulinon The third-party library as the screenshot shows, the criware libs call stak is readable, it can restore the call stack. but the li2cpp part not, it not readable ,and I can't get any infomation form it.

my expected stack trace output is restore the complete stack information, like this.

This is the crash log captured and restored by bugly

this is orgin crash log

I don't quite understand what this is encountered a missing dSYMs banner in console, and how should I check this point.
