One thing to keep in mind, even if your store isn't showing positive growth doesn't mean it's not growing.
If every other store is losing sales and market share like crazy but yours is holding steady or in a slight decline, that means your growth is holding back the losses others are seeing.
Keep doing what you're doing (and consider doing more if you can) and give yourself time for the market as a whole to recover. You might find that your market share will skyrocket in the aftermath.
If you want to watch how your store is doing, Repeat Customer Insights includes several metrics that track your performance over time and give you recommendations for improvements.
