I am having trouble accessing the Bubble page I developed from my phone, as it is taking more than 10 seconds if there is no cache.
(If it’s cached, it loads faster)
Upvote on the ideaboard for Bubble to improve page load speed. Send Bubble support an email asking how to make improvements on your own (maybe there are some things they could suggest)
that is the core of your bubble app, it’s generated from your project and is handled by bubble. There is nothing you can do to make it faster without risking to interfere with bubble’s way of handling it and break your app. Every tool has a tradeoff.
