Hi there, meldeiry.
Thanks for joining this thread. I want to make sure you're able to use the automatic apply credit feature in your QuickBooks Online account.
You mentioned this feature has been selected in your settings but not working properly. To rule out any browser related issues, I recommend first clearing the cache. The cache is used to collect frequently used data to make loading web pages quicker and easier. If the cache becomes too full it can cause viewing and performance errors within the system. Clearing it will remove anything preventing the system from operating properly. Here's how to get this done in Chrome for example:
1. Click the three vertical dots in the top right corner.
2. Select More Tools, then Clear Browsing Data.
3. Change the time range to All Time.
4. Only check Cached images and files.
5. Click Clear data.
The following article provides similar steps for other browsers: Clear cache and cookies to fix issues when using QuickBooks Online
Give this a try and the credit function should start working. Please don't hesitate to reach back out if you have any other questions.
