I went around this programmatically.

Here is an example in Python, easy to get the idea. 
get the page of 100 items and keep paginating until the page comes empty

1. define a client

   jira = JIRA(
        basic_auth=(username,password),
        options= {
            'server' : server,
            'fields' : "comment",
            'expand' : 'changelog'
       )

# define a query    

jql = 'category = Support and updated > startofday(-1d)'
    
    block_size = 100
    block_num = 0
    i = 0
    tickets_list = []
    while True:
        start_idx = block_num * block_size
        if block_num == 0:
            issues = jira.search_issues(jql, start_idx, block_size)
        else:
            more_issues = jira.search_issues(jql, start_idx, block_size)
            if len(more_issues)>0:
                for x in more_issues:
                    issues.append
            else:
                break
        if len(issues) == 0:
            # Retrieve issues until there are no more to come
            break
        block_num += 1

This issue needs to be duplicated for JSD Cloud. The limit is not working there either. I used the following REST API Call:

base_url/rest/servicedeskapi/servicedesk/serviceDeskIdentifier/customer?limit=1000

I've been bit by this as well. It doesn't affect my day-to-day but I needed to work around it in a script I wrote that processed tickets. Would be nice if it worked in the future.

I managed to increase that limit by passing maxResults=100 
(for issue in jira.search_issues('category = support AND createdDate > startOfWeek()', maxResults=500)
 So I am barely managing to do per-day statistics, but it doesn't change the fact that we need more! One would think that a system should be able to handle more than 100 results?

Limit is fixed to 50 and cannot be changed. This is annoying as usually results are way more than 50. Please allow to increase the limit.

limit works, but only for 1 thru 50.  when will it work for more ??

/rest/servicedeskapi/organization?start=0&limit=100
