American Express (AMEX) Transactions Have Wrong Description
It appears that something has changed with the way you pull transactions from American Express (AMEX). The result is that all recent AMEX transactions are coming in without a vendor name, resulting in an UNCATEGORIZED category. If it helps, I have an example transaction from Dollar Tree. For privacy, I removed the real numbers, and replaced them with "what they are".
DOLRTREE [STORE NUMBER] [LOCATION NUMBER] [TRANSACTION NUMBERS]
xxxxxxxxx [TRANSACTION NUMBERS]
Basically, the "DOLRTREE" vendor name has been switched with appears to be a vendor number. Mint does not recognize this, and therefore cannot put in the correct description or category.
Note - this is not limited to Dollar Tree. The same thing happened for every vendor since about 10/25/2015.
Please let me know if you need more information.
