Migrating a well functioning Chrome macro to be used on Edge/Brave/Vivaldi/Arc

Questions & Suggestions

Hi,
some of you may recognise my name because you have helped earlier.
If so, please help again.
The story is as follows:
The macro you helped me setting up has been changed a few times but has been running well every day the last 3 weeks on Google Chrome on a new Macbook Pro 14" Retina (M1).
But, having my best Macbook be occupied by running macros is not optimal especially since I have 2 older Macbook Pro's and another old MacMini.
I migrated the full functioning macro to the Macbook Pro (see system report). For the last 2 full days I have tried back and forth making it work - but failed. I have also made a regression test and migrated back to the new M1 - and it is running well.
Back to the destination migration Mac.
I have taken images from the actual browser and replaced in the macro to avoid any possible rendering/retina, non-retina issues, and I have tested on Brave and Firefox.
Always the same result - so I guess there is something I just oversee totally.
Attached is the macro, a video of what is happening, the images in the macro and the system report.
Hope someone can help out asap, since this in fact is production. Someone (called customer) is waiting for the results...

Keyboard Maestro actions for Browsers require (an activated) ability to respond to Apple Events.

Many browsers, including Firefox and others, are not able to process Apple Events. This is why Keyboard Maestro provides actions for Chrome and Safari, but not for Firefox.

Although some types of KM actions will not work with Brave or Firefox, some actions will. I can't see your actions because you used dropbox to upload your macro. If you use the documented way to upload your macro, more of us may be able to help you:

Here is the macro just used (below the ###).
Here is also a link to a screenrecording used with Safari (changed all to Safari based on input here from my helping hands).

If you need anything else to help out - please let me know asap.
Just for your information, nothing really changed regarding behaviour between last time and now.
Look forward to your feedback.
