For some strange reason this message (which only appears once in my inbox) has some magical properties that enable it to push itself to the top of the list every so often.
Android 8 seems to have issues with DefaultCarrierApp which puts up a notification that won’t go away telling me I have run out of mobile data. This is quite a common issue a lot of people are experiencing as it turns out.
Aside from testing Evolution for email (quite positively so far) I am now experimenting with digiKam as a pseudo replacement for Irfanview. I don’t know whether it can do watermark text or renaming the same, or automatically download images from the camera, so it will take a lot of work to test out these features.
