The Canasta interface issues are so old. The issues could be solved but Pogo won't dedicate the time, resources, and money to fix them. As a subscriber, it's very frustrating to enjoy a game that is increasingly difficult to play given the instability of the interface.
Your programmers and the people who monitor these cases must hate going to work each day. You won't fix the problems so they can't offer solutions or any expectation that things will improve.
Also, your responses suggest that it's the browser we're using, cookies, etc., instead of the instability of the interface for YEARS.
