Buttercam

I really love using this apps but sadly the app takes a long time to respond to each action I chose. Like when I select a special effect on the photo, once I click it will take more than 2-3 minutes for the picture to change effect. Also whenever I try on the template (模板), it could take ages to load or totally not loading at all and says “failed to load cos no connection”. Very sad that the app constantly say connection is bad, connection is slow, there’s no connection... etc, but as the matter of fact, the connections that I used are always perfectly fine and very fast, I only have problem when running this app.. either connecting to the WiFi or 4G, still the same... please help!! 😩😩 I’m using a brand new iPhone 12 Pro Max.

The app is great but I get hella confusion because everything is in Chinese
