I'd suggest you call IRCC to ask, no-one else can tell you.Yes, only this correspondence I received till now and absolutely do not know what is happening because there is complete silence after that update. Hope everything goes well now.
Even I am considering to apply for TRV as this process is killing me
As for TRV: sure, apply. If you want to join your spouse, apply. Might get refused, but you certainly won't get one if you don't apply.
