I may be able to help find the solution, or at least the cause.
I used to use the translate function pretty reliably until it stopped working, and can say for the longest time it worked flawlessly until one day, it just stopped.
When this was, I would have to say probably somewhere between 9 months to a year ago.
So the way to find the issue? Backtracking. Go back through the versions (I’d say jumping back 1 month at a time) until you find a version where translate is working again, and then compare to find out what’s different that might be the issue.
It may be something you guys did to the code, could have been something google did since it’s a chrome based browser to sabotage your variant, but something definitely went wrong in one update from the other, one day it worked, then after a update it didn’t.
