**I closed the block editor after I finished programming the project and exporting the apk file, and when I opened the project again after an hour had passed to make some modifications, I discovered that nothing had been saved and everything I had done was lost and does not exist , I repeated what I did again, but the server does not save anything in the project
Only in screen7 you a re using 41 Clock components, 16 components of the same extension ClickZ and 21 Notifiers....with 20K blocks...Are you sure you cannot reuse components?
20k blocks is too much for only one screen...maybe you can use procedures, or redesign some steps...and 41 clocks? may be you can use the same clock for two or more different purposes?
Initially, I have shortened some of the duplicate blocks using procedures, and I will reduce the number of blocks. It seems that the problem has been solved and the project has returned to working normally. Thanks to all
