Is there a daily limit for the number of variations allowed in Shopify ?

There is a limit on Shopify (not importify) when the number of variants exceeds 50,000 in total https://d.pr/i/6TC65i
If the store has more than 50,000 variants, the number of variants that can be imported is limited to 1000 variants per day.
The only way to import unlimited products to Shopify is to upgrade the Shopify account to Shopify plus
