Hi @sat_miha,
So far I understand, when you open a page, your navigator stores your navigation on its cache.
More time you stay on this page, the bigger will be the caché.
If you are on Mac look at your Activity Monitor and check the memory used by the url of your page.
(Sorry for PC user I don’t know where to look at)
Bubble get quickly to high level of caché because its allows you to work fast, making a lot of improvement in your development within short time, which means getting a lot of information to store. Thus depending of your memory (RAM) you may be stuck quicker.
I have a Mac mini i5 with 6 core with 64 GB, that is supposed to be more than enough but I sometimes get stuck too so I can’t define what level is the acceptable limit.
Safari get stuck quicker than Chrome.
What I do: I just close the page, clean the cache and open my app again from bubble dashboard.
Hope will help.
