Memrise Bug Control iOS Bugs

  1. Create course online
  2. Use it on iOS App
  3. Fix errors in course such as capitalization of letters
  4. Go back and use iOS app

Expected Result: Corrections are now fetched and displayed
Current: Corrections are not directly updated and it seems that pieces of the corrections show up finally after multiple days.

Level: Serious P1 , corrected entries should be fetched immediately when they are available.
Notes: I suspect the code has bad level or level entry meta data comparison. For example, a simple coding solution is to keep a GMT time stamp when the Level was edited and when loading class compare this with the entry online and if differ re-load and populate the local cached set of class entries and then display them.
