Thanks for letting us know!

@tropicadri, can you investigate and see if this is related to the IndexedDB changes introduced in v6.2.0?

@RoLfBOT I can't reproduce this issue on my side. I'm also using Chrome 92 and I used both versions of Workbox 6.1.5 and 6.2.4. I tried on my Mac and I also tried on Android. I tried a simple demo, with one request from the same origin, is there anything else you can share about how you are reproducing the issue? Can you also share the logs from the console? Here are mine as an example:

Thank you!

This issue is happening to me. To my understanding it usually the first queue which nrnever make it to the server. I will try to do some debugging and add more information
