Of course, the last re-entry stamp is the date that is on the TM6, I do the online 90-day for my chum, his TM6 goes back to 2009.
I have my own 90-day login if I need it, though I have to use a different email address than the login for my chum, the only problem I have ever had is with my chum's, rejected because he was on a tourist visa.....😂.....He had been on retirement extension since 2009. I left it a day and tried again, it was approved..🤗
