Description

symptoms: app registers but no push messages are being received, message counter in microg gcm settings panel stays at 0. This used to work some months ago on my previous phone with microg 2.6 on android 8. This is the only app I know for which GCM does not work. GCM works fine for >10 other apps that I use.

versions:
microg: 2.7 ... 2.10
ntv:5.2.3 (2018-01) ... 5.6.4 (2019-09)
android: 9

logcat is attached. I cleared storage of the ntv app right before capturing. Please let me know if you need any more information.

Research direction

Start by reviewing the attached logcat-22862.txt alongside the reported microG, ntv, and Android versions. Reproduce the registration-without-delivery symptom if possible and determine whether the investigation can explain why the ntv app receives no push messages while more than ten other apps work; done means identifying a concrete cause or required diagnostic evidence.
