Sorry, I couldn't get to this earlier. Thanks for the QA @Wangombe! I checked as well, everything looks good to me.

In relation to https://gerrit.wikimedia.org/r/1142408, the result of accepting the suggestion displays the correct action subtype as assistant_language

In the video below, only one translation suggestion event is logged. This functionality was added in https://gerrit.wikimedia.org/r/114013. Notice as well that the translation_memory action subtype now reads as expected with the underscore _.

@KCVelaga_WMF Please verify if the issues you mentioned have been fixed.

With T391958, we've migrated from people.wikimedia.org to https://analytics.wikimedia.org/published/wmf-ml-models/mint/ for external storage. Internally, models will use s3 storage.

A translation suggestion is shown to the user

The events are not being logged as expected.

• In the example below, the first message is "page-Advanced question settings|Translations:Advanced question settings/Page display title/te" - this is fine.
• The second event is of the next message, which I haven't opened. There is no suggestion shown when I actually opened the message. A suggest event is being logged without action_source -- this event shouldn't be logged as there is no suggestion.
• It seems to be happen only the first time a new group of messages is selected.

And here is a mismatch between the actual message ID/title on the interface vs. what's being logged. The selected message is Translations:Advanced question settings/3/te, whereas in the event it is Translations:Advanced question settings/4/te, which is the next message.
