If your havent installed a lot of apps/packages requiring detailed setups on your new RPiZW then I suggest
1. re-flashing the microSD card with the latest Raspbian Stretch with Desktop image
2. I recommend not using NOOBS/PINN, use Etcher to flash image (or Apple Pi Baker for Mac) to microSD
3. after flashing, run update and upgrade. DONT/NEVER USE dist-upgrade on your RPiZW (for now)
the chromium version should remain at:
Version 60.0.3112.89 (Developer Build) Built on Ubuntu 14.04, running on Raspbian 9.1 (32-bit)
and you should be able to use it
lets wait awhile until a new and reliable fix is available....
"Don't come to me with 'issues' for I don't know how to deal with those
Come to me with 'problems' and I'll help you find solutions"
Some people be like:
"Help me! Am drowning! But dont you dare touch me nor come near me!"
