I am from Indonesia.
No, I don’t use any VPN, but the government here often blocks some sites for no apparent reason, even sites like Reddit and Vimeo are blocked here.
Usually, I can access blocked sites by using WARP CloudFlare. I will try using this method.
Edit:
I tried using CloudFlare, reinstall app, still artist art doesn’t appear.
I will change my review on Play Store and consider purchasing the app. This is amazing app with excelent support, but I can’t give 5 stars until this issue is fixed.
