Good luck! I'm sure you'll have no problem getting accepted into the MPP :) I unfortunately don't know the answer about Stripe, as I've never had any issues with it since I've only lived in the US and Europe. Hopefully you're able to get it worked out!

As far as the writing question, I'll miss reading your new articles, but if you're struggling to come up with topics (which I totally understand, by the way, I sometimes do too) I think taking a small break might be really beneficial.
