unable to load tv shows/movies

Evening all,

Bought myself an amazon firestick a coupe of months ago and downloaded kodi onto for the first time, this kodi version being 17.1

Haven’t had any problems at all but recently I have been watching tv shows/movies and it stops playing and I can’t find the link again (or any link to anything), and then the screen sometimes goes black. I then have to go back to the firestick’s main menu, settings, applications, manage installed apps, select kodi, delete cache and force stop. This then fixes the problem but only for a short while (a few hrs of watching tv shows/movies), has anyone had this problem who knows a permanent solution to my problem or knows of any permanent solution? I have already uninstalled and re-downloaded kodi to no avail. Its becoming very annoying now, especially when it occurs when I am engrossed in a good film.

Any help would be greatly appreciated

Mike
