Hi @mlight @lvojnovic - your apps should be working again. We’d pushed out a change to our infrastructure recently which, it turns out, was interacting poorly with older versions of OkHttp (used on Android clients in SDK <=19). This is fixed now, and you can find more information here: https://status.expo.io/incidents/nwqb53dv5g12
We really apologize for this outage – it was unintentional and bad – and we hope the damage was minimal. We’ll keep monitoring, so please let us know if you continue to see anything like this.
As an aside, we do recommend upgrading to a newer SDK version if you have a chance! Not only do newer SDK versions come with less buggy versions of OkHttp, but you also have the option of bundling your JS inside of your app so that it doesn’t rely on a network call to start up. (well, almost – this is not yet true for detached Android apps, but will be when SDK 27 comes out.)
