Issue
I see errors in Sentry either grouped incorrectly under the same issue or the same event separated into different issues even though they seem related.

Error Monitoring
Grouping / Fingerprinting
Symptoms
Different errors grouped together despite having different attributes like titles
Related errors are separated into different issues
Resolution
Sentry uses the event's "fingerprint" to group events into issues. Events with the same fingerprint are grouped into the same issue. By default, the grouping algorithm prioritises:
Stack trace first
Exception next
Message last
You can see the information used to group each issue by scrolling to the bottom of the issue details page and clicking on "Show Details" next to "Event Grouping Information":
The default grouping behaviour can be customised using one of the following options
SDK Configuration:
