[BUG] trying to donate to a 10 different projects on pot fails

[M-Rb3]

Describe the bug

If you want to donate to marketing dao pot to a lot of projects, and select multiple projects on pot page, it 1) takes forever to select, 2) takes forever to enter donation amount 3) after all that, when you click confirm transactions (I have 10 transactions in my case), the modal just disappears. Super frustrating, trying it for the second time, happened once a few days ago, and now the same thing, I don't want to go through all this again and waste 5-10 minutes selecting projects. I know that all or most of these issues are probably related to bos and not potlock in particular, but idk maybe there's a way to fix it in the gateway
