CAMs v2 and v3 not live, but still recording events

Sorry if this has been posted before, but for the past 2 days, I have had all 3 of my cameras not show anything live, but do fine with picking up and recording events. Spent 30 min with ‘chat help’ since I cannot access the actual cameras rt now . Have tried restart, remove app, add app , etc - all firmware up to date - at least per the app. Other than unplugging and starting again, I cant think of anything else. Just curious if anyone else had experienced this? Accessing all with iphone - shared with family member who has Andriod and they are not seeing this issue - wondering if this is an iphone issue??
