"With 1 Question" on Seller Hub

[chickwarrior]

I answered a message on the app 2 days ago. The seller hub displays that i have 1 question to answer. But, when I click on the 'respond to questions' link, I get "The question you are trying to answer is either invalid or older than 90 days. You cannot respond to questions older than 90 days." It is stuck in the seller hub. As if the app and the website are not communicating properly! Have cleared cache several times yesterday, no change! Contacted ebay for business and nothing has changed as of today. Please help!

It's an obvious glitch. You can ignore it or do what I do.. 
There are 2 other places in your seller hub overview that will indicate when you have a message.

If the "Respond to Questions" indicator bugs you, you can switch out of summary format to search format.

You just won't see offers waiting a response, how many ending ( you can already see that info in Overview) and how many watching.

If you receive Offers you get a message regarding it that you will see in 2 places in Overview.

I haven't had my active listing page in summary format for quite awhile. 
I don't use the app.
