Can't interact with any blocks in the Realms environment i.e. can neither create not destroy any block. This only affects one profile running on a Kindle Fire - ok for other users and for this profile on local worlds.
Things I have attempted:
reinstalled Minecraft;
Created new profile;
all user left Realm and rejoined.
