CoinMarketcap had an issue with the OMI token (ECOMI) and lost pricing data for a few days. Now that the issue is resolved, Accointing is tracking my performance on my OMI still, however it is reporting the value as $0.00, therefore my portfolio is inaccurate in regards to this token.
On the mobile app, the pricing data has been stuck since the day of the event in the middle of march, so the value is incorrect, but it is not zero.
Once there, go to Tax Settings, change the Country under Tax Preferences (red arrow), which will result in a currency change (blue arrow), then click on Save.
The new settings will force the system to recalculate all of the pricing in your portfolio.
Once you see the message that the Calculation is finished, switch back to your original configuration.
