Hello friend, you're right, I have that problem since morning. steemit uses the "bandwidth Remaining" to avoid in a certain way the people who publish at every moment, the more level you have and the higher your steem power the bandwidth is higher. According to what you investigate, there is no need to worry because the bandwidth can be monitored, and after decreasing, it is optimized or recovered in a certain period of time. greetings with friend success
