Widget gone under Android 9 (LineageOS)?

[nowakommunikation]

I have CPU Info installed on several mobile devices, older phones and tablets. On all the devices the widget showing RAM status works fine (and, btw, is very useful), not however on my Samsung Galaxy GT-N8000 since recently running Android 9, the LineageOS version.

Before that, I was running Resurrection Remix OS (Android 8, I believe) and the widget worked on the same tablet.

It also works on the original Samsung Android 5 for an older tablet and Android 7 LineageOS for an older phone.

Come to think of it, Android 9 might be the highest version that I have tried it on so far. Might that be a reason?

Although the program runs fine, I cannot find a widget. And under "Settings", the "RAM Widget refresh rate" does not exist.

The Version is 4.5.0 on all devices.
