This issue will be resolved in the next release of Personal, Business and Trust Tax, version 23.2 (anticipated late 2023). If you prefer to update the dividend data feed manually before then, follow these instructions:
Unzip the files and copy them to
C:\Program Files (x86)\Digita\Personal Tax\Dividend\22-23\
This will overwrite the existing files when prompted.
Install these files on any workstations using Digita, Personal Business and Trust Tax.
