Slow work of Ihost

May be somebody, who using more then 50 devices, met the same problem and could suggest help ?
I have more then 120 devices and more then 70 scenes for them. Until some moment quantity wasn’t a problem, but one day Ihost becomes freezing of it’s web-interface. Now practically impossible to edit or add any scenes w\o long pauses for waiting. Time lags could be up to 1-2 minutes and slow work after.
But, if I log-out and stop Ewelink Smart home add-on - everything starts to work normally , w\o lags.

We couldn’t find solution with CUBE support from June 2024 ;-<
