I hope someone can help me. I love this Netflix add-on and have used it for a good while with total success on my Windows box running 18.6.
I have persuaded my 84 year old female friend (who is housebound due to the lockdown here in Spain) to use it also. Unfortunately I am unable to do this for her so I have tried to do it with her via the phone. To her credit she has installed the repo v. 1.0.0 from the zip file and has installed the Netflix add-on. She has an Android box running 18.5. She has signed up to Netflix and has entered her credentials after first opening the add-on and has added some desired streams to her “My List”.
The problem is there is no moving video just sound, which persists even after stopping the stream and going back even to the Kodi home page.
Am I missing some other setting adjustment? I feel a bit awkward as she has paid her subscription and has no use yet.
I would welcome any help and apologise for the long post.

Hi. It is disappointing not to have received any help. That is most certainly not a complaint merely an observation. We live in peculiar times. Further research has told me that the device in question, Beelink GT King, does not support Netflix except up to 540 resolution. My question now is, how do I even get that as I cannot get any sort of stable stream? I must be missing a setting. Both Media Codecs are enabled.
