I am having an issue. When I try to upload a mailing list into contacts from Excel, the program freezes Google Chrome. I've also had this issue uploading images, but recently uploading contacts has been the primary issue.
Hello @Acor44128 ,
Have you tried performing any connectivity troubleshooting? If you're having higher than normal latency (greater than 100ms upload latency will cause issues with our site) for your internet, you may try restarting your router or reaching out to your ISP.
