Spouse visa extension - address change

[dsilvab]

Hello, hope all well.
Apologies if this question has already been asked but I have spent all day trying to find an answer to the question below.
I am a British National - through naturalisation route - in 2014.
I got married in Jun 2016 and my wife joined me in Dec 2016 on a spouse visa. She is an Indian national.
She is now applying for the extension under the same visa from. She is doing so from within the UK, using the online application form on www.gov.uk.
There is a section which asks "where have you lived together?".
We lived at one address from Dec 2016 until March 2019 and now recently moved to another address - therefore, my confusion is: which address should I put into this section?
Because the question asks "have", I am wondering whether it is the first address; i.e. address in the past.
As always, any help would be much appreciated.
Many thanks.

We moved home after the initial visa so similar circumstance to you.

‘Where have you lived together?’
I put our current address.

There are further questions where you have the opportunity to detail previous addresses:

‘Have you lived anywhere other than your current address during the past 2 years that you have not already entered on this application?’
I answered ‘Yes’

‘Please give details of any previous addresses (including country if outside the UK), how long you lived there and whether you lived at this address with your partner’
I answered ‘(1) ADDRESS HERE - My husband and I lived together at this property since I first arrived in England on XX/XX/16. This property was owned outright by my husbands mother. We left this property on XX/XX/18. (2) ADDRESS HERE - Since XX/XX/18 my husband and I have lived together at this property. This property is owned by my husband with a mortgage.
