Mainly posting to follow this thread.
I've been doing light CC hacking using an Amex Platinum for a few years for the travel benefits and just dropped it due to the high cost + no travel due to Covid-19, so the timing was right to jump on the 80k Sapphire bonus.
I applied online, wasn't automatically accepted and received a letter in the mail about a week later "We received your application, please remove the credit lock on your Experian account so we can check your credit", oops, I lifted the lock and called in and was approved about 5 minutes later.
