We have planned database maintenance coming up next weekend. It will start at 8 PM ET Friday, 3/6 and end no later than 2 PM ET Saturday, 3/7.

During this window, schema changes will be temporarily unavailable — you won't be able to add/modify data types or fields, or copy/transfer apps. Live app functionality and other data operations won't be affected. Your end-users shouldn't notice anything. Plan any schema changes before or after the window.
