I'd like to refer to a previous issue I raised in Distributed Trace doesn't seem to work in Chrome above version 71.x
The problem as defined in that thread is that Chrome doesn't seem to allow distributed traces to propagate into backends from at least version 72+. Testing on version 71 shows that the distributed trace is working.
I cannot find any references on the web pertaining to this. The closest is about Chrome implementing CORB for their Content Extension Scripts (https://www.chromium.org/Home/chromium-security/extension-content-script-fetches)
Our worry is that we've made a bit of distributed trace instrumentation work in the past that we are afraid would no longer work in newer Chrome versions when we go live in a few weeks. We are still on development and have not tested this scenario on all our apps but the POC in the above thread seems to paint a bleak picture.
We are wondering if you have any information on this.
Reference screenshots below:
Note that in Chrome 71 a POST with 202 status was attained.
