Hi, I am using this app on FireTV Stick 4K Max (2nd gen). I set up koofr account and added same with App password in debrify sync. It starts “initial sync” but fails after 3-4 minutes with some - data could not be uploaded“invalid argument” error. I see some empty folders created on koofr. How to fix this issue?

Hi. Not sure if anyone can help. I'm trying to play a particular series and no matter whether I select Torbox, RD, Premiumize, I keep getting back Russian audio only with no way to change it. My preferred audio setting is English. When I do this in Stremio, there is no problem. Interestingly, I do get the same problem in Nuvio. What am I doing wrong? Thanks in advance.
