Adjust EXPERIMENT_FLAGS
If you suddenly find that some features are not working, please use DevTools Console to execute the following command:
log_EXPERIMENT_FLAGS_Tamer("yyyy/mm/dd", 1)
where the yyyy/mm/dd is the date you started experience the buggy situation.
Copy the entire result and paste to the comment (or attach as an txt file) to let me debug.
This is based on the old version of YouTube EXPERIMENT_FLAGS Tamer.
It is aimed to turn off most experiment flags while just keeping the necessary features.
