Your application timeline and mine are very similar, I applied on 13th Feb and received my Ack letter on 25th Feb dated 19 feb and we both are still waiting for the approvals. I suppose, Feb applicants are on back burner for now and they are concentrating more on March applicants.
Yes seems that way, but its just a shame as they should concentrate from point of acknowledgement rather than starting new applicants. Wouldn't be surprise if my application was at the bottom of one of their drawers ! But anyway fingers cross, its a nightmare as I'm still waiting to be able to travel !
