Had the same investment account…and others accounts….issues with the 7.6 update yesterday but was able to resolve them all. Tried updating to 7.6.1 today and the process just loops…downloads and installs the update, relaunches, gives the 7.6.1 update notice again. Checked the version and it's still 7.6.0 Build 706.52603.100. Have tried multiple times. Will wait to see if this is another "undocumented feature" that will result in a new update to 7.6.2.
