Hi sorry only just seen this.I speak to my fiancee daily and over the last couple of days they were put back in lock down in Manilla.Offices are not dealing with the annulment or have fewer staff,so there will be more delays.So will just have to wait for the virus to get under control.
Good luck,it can be a long process (even with a bribe) but I think as long as you can prove the annulment is going through you can still apply for a fiancee visa to the UK.
