Multi-lingual Site Not Performing Well

Hey everyone! Happy Holidays. We migrated our website this October and shortly after the migration, we added a spanish version to our site. We installed Shopify's Translate and Adapt app to assist us with this. Hreflang tags and canonicals are also set in place now. This month, Google launched two updates 1st the core update then right around Christmas is when they unexpectedly launched the spam update. From these updates, our sites traffic and ranking has gone down but I'm not entirely sure if it's because the spanish translations are causing duplicate content issues. Other than that, I'm not sure what we could be penalized for. Other details that might help: \- English versions are clean, no more duplicate content/ title/ meta description etc. Currently working on this for Spanish versions \- Robots, canonicals and hreflang tags are in place \- PageSpeed performance is around 61 for desktop and 40 for mobile. Speed Index is around 4s for desktop, 10s for mobile (this is already optimized for us since previously it took about 20s) \- No spammy links or sketchy backlinks
