I've never used WeTV tho, do I need a VPN?
No, as "WeTV.vip" is the international platform of China's Tencent. However, depending on your country (as also with iQiyi), there's a lot of geographically restricted content on WeTV, so I often use VPN (usually to Bangkok) to watch the BLs I want.
On Android, VPN works normally for WeTV, but I always "force stop" WeTV after I finish using it on my smartphone (regardless of whether or not I'm using VPN) because it seems to leave a connection open, which makes me uncomfortable*. On the PC (Windows), VPN for WeTV seems to work on Firefox but not Chrome.
Payment is only via Google Playstore (or the Apple equivalent), so WeTV basically forces you to use their smartphone app.
Both in terms of BL content and as a technical platform, WeTV is the weakest and least essential of the four, but I've been watching it quite a bit lately. It seems that WeTV's own BL productions are often also released on Gaga.
*Not sure if I should be worried about this, but I tell myself that the Chinese authorities already know everything about me (what I had for breakfast today, what colour undies I'm wearing), so what's one more app?
