I got Dynamics 365 trial version and got Sales, Service, Marketing, FieldService & PSA.
But Sales, Service & Marketing apps are together & Field Service & PSA apps are opening separately.
Do I need to do any configuration to all apps together.?
Marketing, Sales & Service are part of CRM from the beginning, Talent, HR, PSA & Field services were added recently part of Dynamics 365 umbrella.
You maybe noticed/noticing lot of changes around Apps/Products to include new offerings. The groupings are just a surprise for everyone in the community.
Even you might have seen Hub apps like Sales hub & Service hub.
