Quick note to say, you are not the only ones stuck waiting for ISA transfers.
I initiated a transfer of cash (no stocks or shares) out of my Freetrade ISA on the 8th of July and still waiting. My new provider confirmed the request had been sent to FT on the 15th and they message me every week to say they are still waiting.
I’m not transferring to 212 and have the same issues - definitely on the FT side.
