This has been fixed in 4.10.3

Sorry, this is still happening in 4.10.3:

I believe @Petro31 recently committed a PR for 4.10.3 to fix this issue. Please re-download the integration in HACS and report back...

It happens to me with the latest version too.

@Petro31, PR 2294 did not resolve this.

@alandtse, @Petro31:
I'm not sure if the fix for this lies in Handling setup failures. I see init.py appears to use a coordinator but I'm not sure where await coordinator.async_config_entry_first_refresh() needs to go, or if that is even the answer.

I do not have the alexa_media raises exception ConfigEntryNotReady in forwarded platform errors so I can't experiment using my own system.

I just installed version v4. 11.0 and errors that didn't exist appeared.

I just had an instance of these errors during an HA reload so I went hunting again.
The previous PR #2336 changed code in __init__.py but I've come to realize now that the code there is only loading the media_player component. The switch, sensor, light, etc. components are loaded by media_player.pyso it looks like it needs the same code change as was added toinit.py`.
