There was a problem relating to the generation and storage of temporary files. This caught us off guard because the test machines didn’t detect this problem. As soon as we became aware of the issue we tracked it down and fixed it. The fix is in Server Update 5.22.3 which was released late last night.
If you have experienced this problem please install PhonePad 5 Server Update 5.22.3 on your Server or Host PC.
We sincerely apologize for any inconvenience this may have caused you.
