Good morning. On January 12, 2021, the browser was blocked from using the adobe flash player. So I solved it by setting the mms.cfg file.
However, on January 13th, a day later, web pages containing adobe flash player were loading significantly slower (at least 2 minutes).
If you know how to solve these symptoms, please leave a comment.
Below is the setting of the mms.cfg file.
AllowListUrlPattern=Web Site Url
My guess, given that there's no useful detail here, is that you didn't allow everything that you needed to. My guess is that there's a two minute timeout built into something that's gating the application from loading. See the enterprise enablement section of the admin guide for more info on how to troubleshoot that. Alternatively, you might just need to watch the network tab of the brower's debugging tools to see what's taking so long to load -- it's possible that the issue is external to you.
