ionic-framework - Total canvas memory use exceeds the maximum limit (224 MB) on ios using ionic 4 and openlayers

Question

we are building an ionic app to show layers on maps using openlayers. Everything is working well on android but on ios when we load the second project we will have the following warning. warning: Total canvas memory use exceeds the maximum limit (224 MB)

I googled it, I think that the problem on ios is caching canvas of the map and when exceed the 224MB the app don’t crash but all layers are hidden on map and gives the above warning.

So is there any way to not cache canvas on ios using ionic? or is there any way also in openlayers?

I will appreciate your help.

thank you in advance.
