I just checked our docs and we have documented that Cypress only supports Chrome 80 and above, so you will be unable to test earlier versions of Chrome with Cypress 10+ for the time being. I do think reintroducing support for older versions is on the cards, but I would guess not in the next few months. Use cases like yours are the perfect example of why this would be valuable though. In the meantime you do have access to older versions of Cypress - for example v9 supports Chrome 64 and higher, and earlier versions might have support for Chrome 53. I am not sure if there's a version that supports both 64 and 53 though. 64 changed things. You will have a more limited version of Cypress in terms of features, but it still may suit your needs. I have a feeling that writing and testing code for SmartTVs has many challenges, and I'm curious about what you will end up doing, so any updates you have are always welcome.

Here one more point. I can't find that Cypress is able to scroll down/up just once(or repeat some certain times). Not to a position or element. Just one mouse scroll up or down. LG TV have "Magic Remote" with pointer on TV, and this Remote have a scroll button. We are overriding that scroll in App to do some specific behaviour.
