iOS: Busy with previous request

[tananaev]

We received quite a few reports about iOS plugin no reporting data.

The common thing I see is this log:

[TSHttpService flush:failure:] Busy with previous request

Could there be some issue with timeouts? Like if there's a server issue, plugin gets stuck for a long time on sending old position without failing fast?

This happens across multiple recent version. Some more log samples here:

I'll have a look.

Btw, any news on Android crash % logs?

[tananaev]

I just published a version with the latest Android plugin. Should have numbers a bit later. With previous release numbers were 10-30% down from the highest point, but still a bit too high. Google Play shows about 2% user perceived crash rate, which is 1% higher than bad behavior threshold.

Those posted logs are from 3 months ago from version v4.

Post the Config you're using. Are you using HttpConfig.authorization?

[tananaev]

We don't use HttpConfig.authorization.

Config looks something like this:
