I got Multiple GUs like around 18 or 19 GU in total but for applicant only 2 are worth noting. The first GU I received after my bio metric was on 9-4-20 where case processing agent check by application and passed it on to Officer, and on portal my BCG changed from We are processing to "In progress" and then after that I received my 2nd GU on 29-7-20 where Officer Checked my file to RFV (Ready for Visa) and on Portal BCG changed again to "We are processing" from In progress this is the date when my BCG completed.
After that I received two GU for Medical extension and later PPR
