SMS Message Counts may be out at certain times during the current month.
SMS Messages may be out for the current month
The SMS totals are completed on a monthly basis and they provide a tally of the number of SMS messages used on a per month basis for each client.
Recently a client's SMS counts were high for their current month (e.g. around 700 for June). Then, when viewed in the month of July, the count had dropped to 210. On closer inspection the issue was being caused because the system was tallying and displaying the messages from the last 13 months, NOT the last 12. Hence the June count was including June 2015 AND June 2016. One some system when the SMS counts are shown, thse may be incorrect for the current month (e.g. once the month changes, the tally will be correct).
This issue is a known bug which has been resolved. It will be out to customers in the next release.
