1- But as I already wrote, somehow I do not have any trial license in my list, so I did not expect that 1 device should use my trial account.
You have multiple free accounts (which, is violating our terms of service). Our automated systems will wipe out all the duplicate free accounts soon. (We do them in batches at random intervals). Or, upgrade one to a paying account and we'll manually remove the other duplicates.
But in your free accounts, yes you're using verified trials. Check every product version you've created. Our system has correctly recorded them. See the “Trial”, “Trial2”, and “MacOS Trial 1 day” versions in your LimeLM accounts.
For example: in free plan, I am allowed to have 10 license keys max in my account, and the users are allowed to deactivate and activate these license keys on max 200 different devices.
Nope. Activations are for people who have purchased your software in one form or another.
Verified trials are for trials.
These topics are covered extensively in our docs:
