For a few days now, I am experiencing a very low performance (lag) of one of my apps on Windows.
In the app editor, on mobile view, it works great, on tablet or desktop view, it barely works.
There is a lot, a lot of lag.
Same issue here with android with an app having just a few tables and less than 1000 Rows. Each click takes at least 3-4 seconds to render. I have already contacted support and hope they find the issue.
We believe at least some cases of this are related to large background images. A fix should be coming soon, but in the meantime if your app uses a background image and seems affected by this, a potential workaround would be to temporarily remove the background image or replace it with a smaller one.
I just quickly tested with my app (which has been slow down in sync on mobile phone) where we pushed GIF image to background image, and I physically feel the improvement in sync time. Obviously new code reaching out to us , thank you for attending to the case quickly.
