All it needed was to restart. A very frustrating day, though. Phones are addicting. I've deleted the COSO app, will use the web browser version from now on. I've had issues with the COSO app before but today was the last straw.
Happy posting!

@jjGravitas I've been using the chrome version for quite a while, here. Works great. A few extra features are available if I flip the phone into landscape mode as the right-hand column with the menu shows up.
