OP
I'm seeing a strange slowdown when testing Lovable GUI changes. What's happening I make changes in the Lovable GUI. The changes are saved/applied and the code is generated/updated. When I open the app in an Incognito/Private window to verify, it takes ~45-60 seconds before the new version appears. Previously this was near-instant. Nothing in my workflow changed (as far as I know). Important note I always test in Incognito mode (both in Google Chrome and Firefox), so browser caching should not be an issue here. Why this is a problem It slows down iteration/testing a lot. It also makes it harder to be sure whether I'm seeing cached content or the latest build. What I've checked so far Hard refresh (Ctrl/Cmd+Shift+R) doesn't always help. Clearing site data/storage in the Incognito tab sometimes helps, but not consistently. Regular (non-incognito) tabs show the delay too if I clear cache first. (edited)
H
already tried all of that
H
is it happening right now for you? probably a system thing on LVBL end atm
C
i'm having the same issue and have also tried all those

Yes and tried 5 times to restore so I think it's their issue

H
they have to consider doing some sort of "outage" messaging when widespread issues possibly happen...in the UI
H
at least I'm a huge fan of the product nonetheless

Same. It has to be a lovable thing. It checks all code and can not figure it out. I wasted a lot of time and credits trying to fix.
C
Also a huge fan. I'd def invest if I could!
M
also when i publish people can not see my webapp as well
C
Really frustrating
H
If I were the Swedes, I'd be holding out until Adobe (or alike) buy them half of the islands in the Archipelago as part of the deal
H
it's still blank canvas, no pun intended, for me
F
Right now restarted working properly
F
Did some of you tried the option "REMIX"? I honestly fear that process....

Hi all If you have a white preview Please tell ai: “add any comment to the vite config” and tell me if it fixes the issue
M
Still blank for me, problem just started this morning sadly
M
same
M
Cleared cache/history and works again not sure if that's a fix or if they fixed
K
Also having this problem. I emailed them but only recieved an AI response.
C
blank for me too - currently panicking lol
C
blank for me too, was working this morning.
M
preview is not working

M
I don't think this is a choice issue rather a bug on lovables end
D
same - clearing browser history helps but after a couple prompts, white screen re appears
N
I have the same problem, any fix?
M
I'll reach out to them and let them know
E
Update: another thing to try is “add any inconsequential npm dependency”. I unwisely did both at once in my repro so now I don’t know which one fixed it (edited)

Thabks, dm me project link please

@Ema I was having the same issue about the preview... So I asked it to investigate. After investigating everything worked again. It suggested it might be an iframe issue.
M
I tried both and neither worked. I'm just opening preview to see changes. lmk if you have any other ideas.

H
Did this automagically resolve itself? I have the exact same issue
T
changed the post title: Lovable GUI updates take ~1/2 minutes to appear in Incognito + live preview not working 9/18/25, 5:07 AM
U
I'm also having issues with the Google Auth and I saw another post with the same so I don't know if these are related but can't set it up
F
