#### Steps to reproduce:

Have you been able to reproduce this issue with just the Firebase Unity quickstarts (this GitHub project)?
What's the issue repro rate? (eg 100%, 1/5 etc)

What happened? How can we make the problem occur?
This could be a description, log/console output, etc.

If you have a downloadable sample project that reproduces the bug you're reporting, you will
likely receive a faster response on your issue.

#### Relevant Code:

```
// TODO(you): code here to reproduce the problem
```

Prima verifica le linee guida del repository e segnala questo problema di Firebase Unity SDK al tracker open source di Firebase Unity collegato. Riproduci il comando `firebase crashlytics:symbols:upload` con il `symbols.zip` generato e analizza il reset SSL segnalato di crashlytics-buildtools 2.9.2. Il lavoro è completato quando il caricamento dei simboli di debug Android termina correttamente oppure il problema viene reindirizzato al componente corretto.

Scritto dal modello di indicizzazione a partire dal testo della issue.
