Gmail not syncing FROM iPhone Mail app TO Gmail
Beginning 22 Jan, my actions on my iPhone 11 Pro stopped affecting my Gmail inbox. Actions I take in my Gmail inbox do affect e-mail on my iPhone, but only e-mails I have not deleted through my phone...manipulating e-mails that I have deleted in the iPhone do nothing (including deleting them and recovering them back to the Inbox). The latter is the issue that most of these forum questions address. I cannot find my issue. This began approximately when I updated to iOS 14.3. I am currently updating to 14.4, but it doesn't indicate that this is an issue being addressed. Any help would be appreciated.
