Quick update from my end ..
I rang the revenue team yesterday and I told the agent I would like to talk to EO / Supervisor. Then I explained my situation and the EO took my issue and told me will give an update around 12.
When I checked my application around 11, it was approved already and then everything went smooth.
The EO called me exactly at 12 and confirmed looks like your issue got fixed.
Looks like they are handling a large number of HTB issues and they will prioritise according to the situation.
