プロユーザーになったとメールが来たが覚えがない

Hi @keikei3 Welcome to the Zoom Community!

You can view your billing, plan and payment information by following the steps found here 👉  https://support.zoom.us/hc/en-us/articles/201363263-Getting-started-with-billing-management#h_1a6cd422-0141-41fb-b044-e9a2b99a0c73. If you are on a Pro account, this will be the place to check :).

Hope this helps!
