I would advice to actually do research before opening the bug instead of just marking the checkbox as there is definitely info available about similar cases that are not related to the ConnectivityPlus at all: https://issuetracker.google.com/issues/231499040

Re-check you project setup as it definitely might be some other package aggressively registering callbacks.
