We all hope and think marketplaces will get back to normal sooner or later.
Staying positive, while sales may have lowered for a few months, this is actually a good time to focus on your brand and your value proposition.
Take time to learn how to optimize your listing. Master the pros and cons of pay-per-click and become a professional in all Amazon features so that you have your brand and your products ready when things get back to normal.
Last but not least, make sure to communicate on a regular basis with your clients, both on and off Amazon.
