Roku Mobile app consumes more battery

Tried to find a way to contact app support, not available. Tried to go through Apple App Store app support, it says Roku doesn’t have that available. Can’t find an email for Roku support, doesn’t seem to exist. The “chat” function isn’t good, and isn’t even available right now. Today my Roku remote app used 40% oh my iPhone 16 pro battery. It’s been using a lot more than I’d expect, but this was crazy.
