It seems that in one of the recent Powerapps releases, the SQL connector will no longer display data from money or smallmoney datatypes (it had previously worked for nearly a year). Refreshed connector, made a new table, cannot seem to get it to load any data from the money fields. Loads all other fields correctly, including decimal.
Thank you for reporting this issue. I can reproduce it locally as well, so I've forwarded it to the team that owns that part of the code. I'll keep this thread posted with more details as I'm aware of those.
