IPTV Application Recommendation

I’m using Chuwi HiPad Max. I am a subscriber to the IPTV provider IPTVBOXPRO (www.iptv.cam). It has its own Android application, but when I install it on HiPad Max and log in, the channel list does not appear. I use it smoothly on my Android phone, but I can’t use it on the HiPad Max tablet. Is there any application you can recommend to me?
