My manual accounts stopped updating daily on February 21st. As you can see, after that date, there is a flat line with the same amount. It was then updated on March 5 and April 4 when I manually changed the investments to add more value/shares, but there are again flat lines after both dates. There is also always a jump at the end, between the current date and the day before. However, as soon as the next day comes, the amount from two days before becomes the same as the flat line amount. The jump is only for the two most recent days.
Performance:
The tickers are correct, and the correct prices are displayed and updated for them daily on the Investments → Portfolio page.
