Is calling Ktor in background thread possible at all ATM? We lost all hope to do that on iOS.

To be clear, if you call it on the main thread, the call suspends and does the actual network call on a background thread. Just FYI. It doesn’t actually do the network call on the main thread.

I understand. The issue is that we want to trigger network operation (it's sync data operation) from background thread (in Android service). So I can't switch to main thread (get illegal attempt to access non-shared $dispatch$lambda-0$FUNCTION_REFERENCE$42@85961ee8 from other thread) nor call Ktor in the background thread.

Yeah, got it. I’m currently wrestling with ktor/ios issues myself, so if there’s a vote for improving support, I’m a +1

I see, just wanted to confirm I didn't miss some magic how to workaround that. Sounds like we have to switch to platform impl on iOS for background part.

That’s pretty common

I'll work on expanding this, but here's a hacky approach for doing GET calls on background threads with native-mt that defers the responsibility of the network call to each platform.
