I have an app whose current version has been out for over a month. Now, since
yesterday I received 6 layout constraint related exception reports (from 6
different users) with the signature shown below. I find that a bit strange,
since layout constraints are not date/time based, so why would they start to
appear suddenly and frequently, and not since the release of the latest
version? Has anyone else started seeing similar reports over the last few days?
