The content (app data, live) at https://actividades-con-entrada.bubbleapps.io/actividades
is ONLY shown in Chrome, but not at Firefox or Opera.
Yesterday I could see this app data at the live version in Firefox (because I have it as startpage in Firefox).
But today my app displays empty fields on Firefox and Opera in my live version.
I have not alowed some updates in my browsers and I have not made any changes at my app for a long time.
This change happened between yesterday and today in the morning.
What could be the problem?
And what could be the solution?
