Hey, @Kasimjh for large projects you should use a VPN also. Use a VPN that is in the US, as that’s where the Adalo servers are located. Loading times in the editor will be significantly faster when accompanied with Firefox.
Also make sure to turn off Lottie Animations in the browser, and rather than uploading images into the image frame in the browser, paste the URLS. I hope this helps. I have a couple of projects that have 200+ screens, and the VPN made all the difference… But make sure it’s a good VPN, Some of the free VPNS are terribly slow.
