Outdoor cameras not updating views timely (up to 10mns delay)

Hello,I have 8 cameras installed and 2 of them are not updating views within 40 secs. These 2 are 2 of my outdoor, plugged-in cameras.All other cameras showing on the app are updating Live ZViews within 40 seconds.These 2 keep going past 40 seconds and up to 10-12 minutes before the views are updated.Strong signals. Strong RSS 46-50 Green and they are both online. They are both up to date in terms of firmware.Any suggestions on how I can fix these 2 and get these to work properly like the others, since they have a signifcant delay updating views past the normal 40 seconds and well into 10-15mn before views are updated from these 2 cameras.Much appreciated.
