some weeks ago I had tested admob free plugin and it was working. Now I want integrate it in my app and it does show only a black rectange where the Ad shoud be. Interstitual isnt showing. No Error or something else. Creating a app from scratch shows the same issues.
I think it depends on a conflict with a newer version of something.
Can somebody provide me with a working starter app (ionic 3.6 or higher) that only include a working admob free plugin. So that I can figure out from a working starting point, where my issue is?
Thanks in advance and best regards, anna-liebt.
