Card Export Tool Fails Constantly

I have tried several times now to create an export list using the inventory tab and selecting cards I wish to put into a CSV. file. I have approximately 3,700 cards in my inventory, and whenever I select the entire collection (which is not a quick process btw) when I go to click the export option many red error boxes pop up in the bottom right and don’t allow me to continue. This sucks, as I’m new to MTG and this is the only inventory app I currently have. Me not being able to export my collection makes me not want to use this platform anymore, honestly. Right now, I feel like I’ve wasted a lot of time adding my collection to your app only to not be able to adequately access it
