I have a form with two master - Detail in the desktop version work well, but In the mobile version, the forms do not appear ( 404 error Pages not found). This happens after the last update of this month SC. HELP

Had the same problem in the past, went away but seems to be back in another app. Still not sure of the cause/ real solution but the workaround used then is here

Similar issue I just posted on another post

Found sort of a solution…

Simply change “open in new tab” to yes and the need for refreshing goes away…also the master/detail works good.

It does change the layout a little, but for me, it actually improved it.

Hopefully someone find this helpful
