Every one of my TDI certs has taken at least a month to be registered on the online app - just wondering if this is slow processing, an issue with the dive center or something else.
Occasionally, very occasionally, cards are processed and mailed and go astray in the mail. However, 99.99 percent of the time, TDI and SDI turn diver cards around in a couple of days... instructor cards take longer... but not a month.
