My offer to work with you on this (for free) still stands if we can make it happen (E225: DOM failed to be ready in 30sec - #3 by TheWhippinpost).
It seems this may still be symptomatic of several stubborn issues that’ve lingered for several years whilst migrating UI.Vision to Manifest 3.
From a personal PoV, I am concerned now that the temporary fix in Chrome to continue running Manifest 2 extensions will end mid next year; ie, v.6.2.8 will cease to work.
From a wider PoV, this could be affecting users who are unaware that their data-collection is missing data.
I will do my best to accommodate you in the new year if you can make it happen.
