There have been a lot of users running into bandwidth limitations recently. The Steemit dev team has been reviewing the issue and is working on changes to the bandwidth formula that will improve the situation. They opened GitHub issue 1257 to improve the formula. and have also already checked in a pull request to change. Based on what has been reported in GitHub, it looks like this will be available soon.
The bandwidth calculations are not done as part of consensus, so they do will not require a hardfork. Version 19.1 will be a softfork. Witnesses should test and review the changes, and upgrade to version 19.1 as soon as possible after the official release is made.
For those interested in the technical details, here is the text from the issue:
