Bests & Worsts Reviews from Amazon

I have had a digital subscription for years, and am able to read the Times on my laptop, iPad, and Android phone. But not on this app. Even though it shows I am logged into my account, I cannot read more than 10 articles per month. I have chatted with Times customer service about this, who have no idea, insisting that (1) my subscription does work on the Fire, and (2) nonsensically asking me repeatedly to "clear the cache and cookies" - even though I tell them that this is an app (their app!), not a web browser. Anyway, even deleting and reinstalling the app has no effect. So no Times on the Kindle, without buying a second digital subscription.
