One Reddit user with the username 5h3r10k shared a workaround that some others said worked for them. “Update: I just updated the Google app, then force stopped and cleared cache for Google, and it’s working now. I needed to force stop and clear cache though, even after updating it still didn’t work until I did that.” This was confirmed by xiaomifan01 who wrote, “After updating the Google app (14.46.33.28) and clearing the cache it’s possible to add the widget again on my Poco VAYU running A13.”
