delayed notification issues

[doug95]

I had been having strange issued on my S7 - I'd often get them late, or grouped together after a long delay. I performed a factory reset on my phone, and for a while it seemed to be working correctly again. But after a couple weeks, the same delayed notifications continued happening. Has anyone else seen this sort of behavior with their S7?

I've seen it with a Pixel 2, so it may be Android, not the S7.
