The ones related to push notifications can be ignored. They just indicate a temporary error when attempting to send push notifications. It is usually due to load or communication issues with the push notification endpoint (usually controlled by Google/Apple etc.)
The ones related to sitemaps can be solved by either upgrading to the latest version which should be available from your customer area or by removing the Google URL from the sitemapAutoSubmit
option.
EDIT: It looks like you are already using the latest version. That version was installed today. The sitemap errors shouldn't happen anymore.
