Constant issues with connection

For the past month or so, I've had non-stop issues with the Zoom connection when I attend meetings. It used to be totally fine and suddenly nothing but problems. I haven't changed anything. I've done all kinds of troubleshooting and tests. I close my Internet tabs, I constantly restart my modem and computer. I do the speed test and it's phenomenal. Don't have issues with anything else other than Zoom. I even tried from different platforms (app, mobile, browser) and it's all the same so I know the problem is directly with Zoom. Can't even see a way to contact Zoom! What can be done about this? Please help!
