Looks like in Chrome
Version 56.0.2924.87 (64-bit), post
Web 8.1.1 upgrade has some js issues which are not allowing me to open components that have media associated to them.
Also, notice overall slowness reported from editorial team for mundane tasks like browsing, opening and associating and when saving components in Chrome, it leaves them in checked-out state.
Does anyone else experience the same with Chrome or these js errors when trying to open a component, possibly of a certain type or with multi-media assets or media from DAM system associated?
