@shashankrt did you continue maintaining the 30L TRV even after getting M4B? Or was switching to 10L savings balance after getting the M4B card sufficient?
Also, in your opinion, instead of 45 days of maintaining TRV, is the real criteria, one OGS statement containing TRV?
Please let me know. This will be most useful. I am in the process of trying to get the M4B with a new Burgundy account
