iOS: Operation Stopped error

[kkuepper]

We occasionally get support tickets complaining that they can't play a certain track.

My theory is that iOS is loading the file but runs into some kind of error. Then that errorneous response is cached, so that the next time it's trying to load the track, it gets the same faulty response.

query:
union app("AppCenterExport-BMM-Android").customEvents, app("AppCenterExport-BMM-iOS").customEvents
| extend properties = parsejson(tostring(customDimensions.Properties))
| where properties.technicalMessage contains "Operation Stopped" or properties.technicalMessage contains "The operation could not be completed"
| extend UserId = tostring(properties.AnalyticsId)
| summarize count(), dcount(UserId) by bin(timestamp, 1d)
