Schedules messed up after update to 1.8.6

Hmm, this is an oversight - we will get it fixed asap

To work around the issue you can run the following SQL in your DB container:

INSERT INTO `permission` (entityId, groupId, objectId, view, edit, `delete`)
  SELECT entityId, groupId, dayPartId, 1, 0, 0
   FROM daypart
    CROSS JOIN permissionentity
    CROSS JOIN `group`
  WHERE entity LIKE '%DayPart' AND IsEveryone = 1 AND (isCustom = 1 OR isAlways = 1);

Instructions for doing that with Docker are available here: How can I run a SQL command when using a Docker Install?
