I have used Microsoft Edge, Chrome and Safari… have trouble on all of them
I think I found a workaround! I am using MS Edge. Before doing any editing to team info / logos - go directly to your uniforms > helmets. You SHOULD be able to see the generated default home helmet. Click through to stadiums > Program. Making sure everything looks good and loading correctly. Go back to your team edit screen and try uploading images. After days of trial and error it seems this is the most effective way to generate your logos and finish a full Teambuilder edit smoothly. I had no issues. I made sure I saved progress after each uniform was completed. Hope this helps!
