Domoticz lite app issues after update

[RMvanderBijl]

Domoticz Lite App latest version
Domoticz latest version (Raspberry Pi 3B)
Mobile phone Oneplus Android 13

I have just upgraded Domoticz on Raspberry Pi via Domoticz webpage.
Now the App is not showing the bulb swithes any longer (instruction: 'çheck settings')!
I removed and reinstalled the App but this issue remains.

Domoticz webbrowser: 'Basis authentification' is set to 'on'. Password and username are not changed (= basic defaults (admin/domoticz)).
Domoticz Lite App: 'Server name =DEFAULT', HTTP, port 8080, user name=empty, password=empty. Succesfully fetched server configuration.

Log file: Depricated: Page LoginCheck! Use command instead!

Can anyone gives me some advice?

Many thanks in advance.
Kind regards, Ronald
