> Interactive Brokers' software is usually very solid.

Except their web portal. 40-50% of the time it is unable to load my portfolio data (even without the current market value, just the number of stocks and cash balances). At the same time I log into the mobile app, it forces a logout on the web app (why?) and it is able to load the balances and portfolio. No explanation. Same network, no adblocker or other browser plugin.

The single session thing is annoying. I'm guessing it is related to their various data provider regulations. The large brokers can get around this because, well, you are not really seeing pool depth and the like.
