After the update I'm back to free version, even though my Guru subscription is not outdated. What should I do?
Guru version is tied to the e-mail account you used for purchasing the app, so please make sure you're logged in it. Then restart the app completely, swiping it out of "Recent Apps" list. After launching the app you should have your Guru version back.
Keep in mind that multiple Google accounts can cause the app to go back to free version and then again to Guru, causing some Guru options to be disabled. (see the next question)
