Looks good, @manueliglesias! Great job!

[Ashish-Nanda]

Great work @manueliglesias 👏

[rpostulart]

Is this the best way to report the issue, or in one of the earlier issues?

Still an issue:

I get this error after yarn add @aws-amplify/datastore@2.1.3-unstable.5

Then when I clear cache this error

Then when I change

this.init = DataStore.observe(Model).subscribe(); to DataStore.start()

It works great team! Congrats.
I added 1000 records to DB and now performing on chrome as well safari is amazing.
While before with not more than 300 records I noticed huge performance issues.

Keep up the good work!

[dabit3]

Thank you @manueliglesias this is awesome 💯

[rpostulart]

@manueliglesias I again notice performance issues on Chrome.
See master repo: https://github.com/alowa-apps/kwizz
You can check it out by make a quiz and log in with a game code when you have cleared the browser data.

Shall I make a new issue for this?

[rpostulart]

Ps. I only notice this on chrome on Android but not on the Mac.
