Problem install m3u on kodi 17.1 (pc, android tv and rpi same worries)

Hi everybody,

sorry for my bad english but i speak french ! i’m new member and i come from belgium …
i use kodi 17.1 on pc, android tv and with a rpi

I read and reread everywhere but I have not found a solution …

I bought a file iptv m3u…. and I am quite happy, a few lag from time to time but it remains correct

My problem is not a question of how to install or other but I have my file on a usb key, I install it in kodi and this both on android tv and on a raspberry pi as soon as (android Tv or rpi) my channels have disappeared !!! And I have to repeat the procedure (pvr simple client etc etc …)

I have to omit something but what?
on pc with windows 10 run ok !

thank you in advance for your help
