Vietnam e visa processing time

Hey everyone, I may have made a mistake with timing so hoping for some guidance.

I’m leaving Japan today, and flying to Taiwan for a couple days before my flight to Vietnam on the 31st at night. I just did the e visa application while waiting to board my flight (Canadian passport)

I’m wondering if I’m in a sticky situation. This is the first time I’ve had to apply for a visa so I’m new to the process.

Any suggestions would be great!
