Premature exit of Vuforia Chalk (2.8.3) on iOS when "Start Session"

[ISSUE]

If a Chalk User is registered with  non-English characters, Vuforia Chalk app on iOS will prematurely exit when "Start Session" is clicked. 

This "Start Session" is only used by the user with HOST privilege.

#This issue is scheduled to be fixed in the upcoming release.

[ENVIRONMENT]

Device/OS : iOS (iPhone or iPad)

Vuforia Chalk version: 2.8.3

[WORKAROUND]

Delete a registered user and once again add a user using English characters only.
A user name is cached and updating the user name doesn't fix this issue. 

It's also best to Log out from Vuforia Chalk App before deleting a user.
 Settings > My Account > Log Out
