App Review delay

Same issue. Been few days since we have submitted the app for review and its stuck in 'Waiting for Review'. Then we rejected and resubmitted thinking its stuck in some queue, but still 'Waiting for Review'. What I find interesting is that normally, soon as an app is submitted for review, one gets emails like 'Submitted for Review', 'Ready for Review', 'Waiting for Review' - we have zero such emails this time. Which makes me think if the app is even in a review queue or is there a larger technical issue at Apple's end where App are just not being able to submit new versions. All this after having paid versions of developer accounts, going through stringent processes and still issues like these. Why make developers suffer losses of time and money like this. @App Store Connect team - please respond to the forum - so many developers like us are writing but no responses.
