I had to drop my opinion of this app for inconsistencies. I have this on my Samsung phone and Samsung tablet. On the phone, the operation is still functional. However, it will not function properly on my tablet. It opens for about 4 seconds and then closes. If I open it again, again it closes at about the 4 second mark. At that point I get a message that the program is not working correctly. I notice this beginning on 31 January 2022.
