Get Emails (V3) folder incorrect after flow has been shared using Send a Copy

[YorkshireMidge]

I have a flow where I use Get Emails (V3) and a subsequent delete step to automatically delete a message my flow has just sent - so it tidies up after itself.   This worked absolutely fine - until I used Send a Copy to share it, where on my receiving test account,  I got the following error message when I had set the flow up on there.  

As of May 6, 2020, shared mailbox support was added for certain operations with an optional 'Mailbox address' parameter, allowing you to specify a shared mailbox address for your operation to access. If you were using this operation prior to May 6, 2020, you will need to explicitly update your operations to specify the shared mailbox address. Please follow the Office 365 documentation for more information: https://docs.microsoft.com/en-us/connectors/office365/#shared-mailbox-support

This error is nothing whatsoever to do with what my flow is doing, as my test account is just a standard user one. 

On further examination. it appears that Get Emails (V3) hooks into the originating account's Sent Items folder which is just daft as far as I can see.   i.e. when you look at the code, instead of the folder path being Sent Items, there is a full folder ID in there.  I assume this is the cause of the 404 error because my sent items folder won't be accessible to the receiving (test) account. 

The only way to get rid of the problem on the recieving account is to edit the flow and remove the Get Emails (V3) step, and put it back in with the same settings - where it picks up the receiving account's sent items folder and then works perfectly well.  i.e. you can see when you look at the code that the folder ID has changed.  I'm using a template precisely so my users DON'T have to mess around with a flow to get it working, so this isn't acceptable as a workaround. 

Any ideas why Microsoft would have done this, and is there any way around it? 

Thanks.

Just initialised a variable on my original flow and set it to Sent Items, and put the variable in Get Emails (V3), and it seems work OK when it is distributed now.   Just in case anyone else hits the same issue.

I just wanted to say thank you.  I spent a full day trying to understand why I was getting this error.  I finally came across this post which describes the same issue.  I changed mine from V3 to V2 and it is working fine now.
