Traccar Manager on iPad doesn‘t work properly after update to 6.15.3

Hi,
After Update my server to 6.15.3 Traccar Manager on my iPad Shows still app version 6.14.1 and the app doesn’t work properly (most settings pages don’t work).
The problem neither occurs on my iPhone nor in the browser.
App Store shows the newest version installed.
See screenshots.
What can I do?
Thanks in advance,
Daniel

Now, a few hours later, the iPad shows App Version 6.15.3 as well and works fine.

So, the issue seems to be solved. Even if I don’t understand what happened.

You need to wait and then click refresh. Or reinstall the app. This is simply cached version.

Ok, thank you. Makes sense.
