Thanks for reaching out and sorry that you are running into this issue!
Looks like we're missing <# of missing dSYMs> dSYM files for Version <VERSION> Build <BUILD> that we need to process crash reports. For data fidelity reasons, we only display crashes that we can symbolicate, so if you can use the following command on your terminal to find these files:
mdfind "com_apple_xcode_dsym_uuids == <UUID>"
Replacing <UUID> with following UUIDs:
and send me the zip file, I'll upload the dSYM for you right away and you'll start seeing those crash reports come in. I have also attached link that give you more insight on missing dSYMs:
Let me know if you have any further questions :)
