I believe so. I had very similar issues as OP described, and after a while of trying to get these files playing, the app would crash with some message about running out of memory and that it would be restarted. After searching online for people experiencing something similar, I found somebody on reddit saying they turned off all those agreements and it helped them. I tried it and all the issues were gone after that. I ticked off everything except terms of use and privacy policy, and for my tv the agreements were located in support > privacy and terms > user agreements.
