(In reply to Cristina Horotan [:chorotan] from comment #16)

This bug has started to frequently fail after the landing of Bug 1827572

Punam, can you please take a look? Thank you

Looks like intermittent failure due to race condition when screen impression call skips order and is not last call which test expects. WIll submit patch to filter out screen impression call explicitly before assert in test

@ryanvm linux debug disable seems to resolve a different issue. Code has changed since than, I can try enabling these tests on my local and send try run in linux debug mode and update bug if its safe to revert. Thanks
