GET /1.0/profiles email filter does not work when certain email address are used via Microsoft Azure HTTP request

Hi,

When using more complex email addresses in the 'filter' query of an HTTP request from a Microsoft Azure Logic App to 'https://api.squarespace.com/1.0/profiles' , no matching responses are returned. 

• The email addresses I'm using in the 'filter' query are being correctly encoded
  • e.g. 'example01customer+01@gmail.com' is encoded to 'example01customer%2B01%40gmail.com'
• When using less complex email addresses, the Microsoft Azure Logic App does return the expected response.
• Using the exact same values in a call via Postman (e.g. host, URI, bearer token, User Agent, filter query), I do get a matching response.

I've tried using both the Azure Logic App built-in 'HTTP' connector and a custom connector, but see the same issue with both.

I appreciate it seems highly likely that this is a Microsoft Azure issue, but I'm hoping someone on this forum may have seen a similar issue and found a solution.

Any guidance appreciated.

Thanks
