How to solve problem with Teamviewer host on Android?

Hi!
I have a Samsung SM-G532MT phone.
I installed Teamviewer Host and used it for a long time without giving problems.
But after the last update the app stopped working. I have already tried to perform the following procedures:

-I tried to reinstall the app on Android;
-I tried to configure the permissions;
-I tried to reinstall TeamViewer on the PC;
-I tried to configure TeamViewer host as Administrator;

None of the procedures worked.
