Free trial for Plus subscription

Is there some way of trying Plus functions before switching to it? In particular, I’m interested in the LynxAI extra functionality. I use a similar app outside Lingq and would be glad to move this conversation activity here as well, where the chat is linked to my vocabulary list, especially since the price is comparable. But I want the chatbot to explain all the grammar and vocabulary I get wrong in the conversation, not just some major errors. It is probably, what the Tutor mode does, but I found no explanation and also have no way to judge how good the “enhanced engine” is. It would be really nice to get some free trial or something like that.

Another question is how switching to plus actually works? I have a two-year subscription, that will end in December. Does it mean that I would need to think about switching to plus then? If I do it now, would I need to pay the price difference, or the full Plus costs? What if then I decide that I actually don’t need Plus and want to downgrade?

This, I’m thinking too recently. If we can test it even for 1 day. We could see it’s effectiveness.

At the moment we don’t have a trial available for the Plus plan.
