Frequency of stop syncing is too often

I installed this app on my brand new iPad Pro 9.7 for not even a month but already have to delete & reinstall it for more than 5 times due to this syncing problem. Itll show unread new emails on the notification screen but nothing new in the inbox when I go to Gmail. Something must be wrong here and hopefully it can be fixed soon!!
