I went to do my 90 day reporting last Tuesday but they refused to do it because I had no TM 30 slip in my passport. The reason being I went to Malaysia for 6 days in October so I was 90 days over for reporting. I had to queue up for two hours then I got the TM 30 then my 90 day reporting and no fine. In June 2020 they changed the rules if you went abroad and came back in on a re-entry visa and went back to the same address you did not have to do a tm30. So have they now gone back to the old rules.
