Please update the app. Make sure you are installing version 4.18.2.
If you already installed 4.18.2 and the problem persists, try reinstalling.
I have the same problem on an android.
Same problem in Android V4.17.4(284). Makes using the App with long lists very annoying. Otherwise a wonderful product which has been extremely reliable and easy to use.
Same with me
Same prob today.
Makes it useless for portfolios over 10. Useless.
