hey there,
started using growthbook, love the tool so far, the possibility to customize stuff and the MCP integration.
Just a small note, I really struggled to upgrade:
1. in the first page i've entered VAT and only after I clicked PAY I've got an error that VAT is incorrect and all other custom data got wiped out because i had to go step back to check
2. After retrying full payment flow it failed with some random error (screenshot attached)
3. After third try (using all the same data) I managed to upgrade successfully.
There is no issue now, but from business perspective imho having a well working upgrade form is important to have as least friction as possible. cheers
