I have been using Kodi 16.1 for some time and also tested all the streams which are legal streams from news site that anyone can access. Works perfectly in other apps and older Kodi versions.
Have been testing Kodi 17 with both IPTV simple Client and the streams as .strm files. Its extremely slow to switch or load most streams, about 2 minutes which work perfectly in other apps, and older kodi versions. Some streams take multiple minutes and result in a crash. The problem is definitely not with the streams I have double tested them.
The issues im having are from the first beta I tried, which was about beta 4, until RC2 and Nightly Krypton Builds. The problem exists on Windows 7 64bit and another computer which is windows 10 64 bit. I haven’t been able to test android yet.
Im hoping someone can help or suggest something to do with settings, or if there are known issues with certain formats in these versions of kodi.
