I have had a client school have the same kit installed over the summer replacing some Cisco Kit that had been rock solid for years, the upgrade to the Forti kit was done under the CTC Scheme, we had exactly the same issues as you describe where that kit wouldn't connect in the classrooms where the AP's were but only for some classrooms, go into the next classroom and they connected straight away. Together with the installer we worked out that disabling the 5G Radio allowed the devices to connect, but when 5G was enabled they wouldn't connect. Firmware upgrade to 7.4 on all the AP's and Fortigate Controller seemed to resolve the issue, but not after a lot of back and forth between us, installer and Fortinet. However a different issue still remains in that a Wireless Bridge to a remote building keeps going down without any explaination - issue still being investigated
