I was able to find out on the Tenscent Video app. I had to pay for it to see all the episodes, that might not be the case now that it is done airing.
Here's the link in the Google play store. https://play.google.com/store/apps/details?id=com.tencent.qqlivei18n.us
I used FlyVPN to watch Remember 15 on Viu. Different platform but it’s free so it doesn’t hurt to try if it works.
I know that if you’re using a pc browser and not an iPhone you can try opera browser, comes with a VPN and it’s free. I’ve heard some users on here use that but since I mainly watch on my phone I haven’t tried it.
I think it's available on Amazon.
Someone else suggested setting ExpressVPN to Spain, and that worked. But if I have this problem again and can't find a server that works, I'll definitely keep that free trial in mind. Thanks again for helping out :)
