Problem with UDGrid not updating

I have a form I am building that runs 1 of 2 Exchange cmdlets based on user input. The 1st cmdlet is a simple Get-Mailbox and this usually completes in under 5 seconds. The 2nd cmdlet is Get-Mailbox -ResultSet unlimited and this usually takes up to 10 minutes to complete. The problem I have is that the 2nd command never updates my grid with data. It just continues to show a progress bar flashing across the grid. I ran the code directly within powershell and i get the correct data back so I know the syntax is correct. What can I change to make my grid update when executing long running endpoints?

My code:

New-UDInput -Title "Search Criteria" -Content {
        New-UDInputField -Type 'textbox' -Name RecipientEmail -Placeholder 'Recipient Email Address (Seperate multiple addresses using semi-colon (;) / Leave blank to search all mailboxes)'

        New-UDInputField -Type 'textbox' -Name SenderEmail -Placeholder 'Sender Email Address'
        New-UDInputField -Type 'textbox' -Name AttachmentName -Placeholder 'Attachment Name'
        New-UDInputField -Type 'textbox' -Name Keywords -Placeholder 'Keywords'

        New-UDInputField -Type 'date' -Name StartDate -Placeholder 'Start Date'
        New-UDInputField -Type 'date' -Name EndDate -Placeholder 'End Date'

    } -Endpoint {
        param($RecipientEmail, $SenderEmail, $AttachmentName, $Keywords, $StartDate, $EndDate)

        Set-UDElement -Id "emailsearchresults" -Content {
            New-UDGrid -Title "Search Results" -Headers @("Name", "Item Count", "Size", "Success") -Properties @("Name", "ItemCount", "Size", "Success") -Endpoint {
                $RecipientList = @()
                $SearchResults = @()
                #Use this SearchQuery for testing.  
                $SearchQuery = "Subject:'I/O problems' AND received:11/08/2019"

                if($RecipientEmail -like '*@*.*'){
                    $RecipientList = $RecipientEmail.Split(';').Trim()
                    foreach($Recipient in $RecipientList){
                        $SearchResults += Get-Mailbox $Recipient | Search-Mailbox -SearchQuery $SearchQuery -DoNotIncludeArchive -EstimateResultOnly | Select-Object Identity, ResultItemsCount, ResultItemsSize, Success | Where-Object { $_.ResultItemsCount -gt 0 }
                    $SearchResults += Get-Mailbox -ResultSize unlimited | Search-Mailbox -SearchQuery $SearchQuery -DoNotIncludeArchive -EstimateResultOnly | Select-Object Identity, ResultItemsCount, ResultItemsSize, Success | Where-Object { $_.ResultItemsCount -gt 0 }
                $SearchResults | ForEach-Object {
                        Name = $_.Identity.Substring($_.Identity.LastIndexOf('/')+1)
                        ItemCount = $_.ResultItemsCount
                        Size = $_.ResultItemsSize
                        Success = $_.Success
                } | Out-UDGridData 
    New-UDRow -Columns {
        New-UDColumn -Size 12 {
            New-UDElement -Tag "div" -Id "emailsearchresults"

ok, this may be fixed in 2.7.0. I’m running 2.6.2 right now because I’m having ADFS issues with 2.7.0. I just installed 2.7.0 on a test machine and the long running script successfully updated the grid.

There were some changes to how endpoints are managed in 2.7 so that’s likely why its working. The ADFS issues are on my radar. Are you seeing it redirect internal URLs\white screens?
