Unable to reply to Messages and Offers

[mipx01]

Last week noticed unable to reply to Messages and today having received an Offer am unable to Respond. No point in having Messages if we cannot reply!!

Suggest if not already using it you use the Seller Hub.  Also read Announcements.

Am using Seller Hub!! Have also read Announcements...cannot recall reading about being unable to reply to a message or indeed respond to an offer from Messages. Answer certainly not a solution, nor indeed very helpful. Expected more useful information, but never mind, the more I read from so called 'experts' the less confidence I gather. More sensible solution to this problem awaited.
